Bathroom project - T&J8x10 Bathroom Remodel Cost in Wisconsin: The Short Answer
A mid-range 8x10 (80 sq ft) bathroom remodel in Wisconsin typically costs $14,400-$22,400 all-in, which works out to roughly $180-$280 per square foot for mid-range finishes in the current 2026 market. Budget refresh work on the same room falls at $8,000-$12,000 (roughly $80-$120/sqft), and high-end or full-gut remodels with layout changes push $24,000-$40,000+ ($300-$500+/sqft). These figures reflect current Waukesha County and greater Milwaukee metro market conditions, and they account for the 4-6% cost bump the small-bathroom category saw going into 2026, based on regional contractor pricing surveys and T&J's own project database across roughly 90 bathroom projects in the last three years.
Here's the piece most homeowners miss when they're comparing quotes: the same 8x10 room can legitimately price at three different points, and it isn't contractor markup. It's scope and finish. A $12,000 bid and a $22,000 bid on the exact same room usually means one contractor is doing meaningfully less work, using an allowance instead of a specified fixture, or leaving line items off the page entirely. Before you open bid number two, you need to know what "normal" looks like for this specific room size in this specific market. For broader context on room-size pricing across the state, we cover the average bathroom remodel cost across Wisconsin in a companion guide.
What's Driving Your 8x10 Quote: Cost Per Square Foot Explained
Bathroom remodels in 2026 price out at $70-$250 per square foot for typical projects across the Wisconsin market, with the wider industry range running from budget refresh at $80-$120/sqft to mid-range at $180-$280/sqft to premium at $300-$500+/sqft, according to current 2026 regional contractor pricing data. Apply those tiers to 80 square feet and you get the honest reason the same room can price anywhere from $6,400 to $40,000: it's what's going into it, not who's installing it.
Labor accounts for 40-65% of total bathroom remodel cost in the 2026 Wisconsin market. On a $20,000 8x10 remodel, that means roughly $8,000-$13,000 in labor across the carpenter, plumber, electrician, and tile-setter.
Bathroom - T&JThe reason this matters when you're comparing bids: labor is largely fixed by what the job actually requires. A licensed plumber charges the same to rough in a relocated toilet whether your vanity costs $600 or $2,600. So when bid A comes in $10,000 under bid B, the delta almost never lives in the labor line. It lives in the materials spec, the fixture allowance, and (most often) the things that got quietly left off the page. Waukesha County trade rates run above the rural Wisconsin average because of licensing requirements under Wisconsin DSPS and the compressed building season, which is another reason a suspiciously low bid deserves a hard second look.

Ask each contractor what percentage of their bid is labor. A fair mid-range 8x10 quote should show labor between 45% and 60% of total. Well outside that range on either end is a signal something's off in how the scope was built.
Line-by-Line: Where the Money Goes on an 8x10 Bathroom
This is the section to open next to your bid sheets. Every one of these lines should be visible on a legitimate 8x10 quote in some form, whether as a specified item or as a realistic allowance. Figures below come from 2026 regional contractor pricing data cross-referenced against T&J's actual invoicing from Waukesha County bathroom projects in 2024-2025.
| Line Item | Typical 8x10 Cost (2026) | Notes |
|---|---|---|
| Demo and prep | $1,000-$2,300 | Higher if going to studs or removing cast iron |
| Plumbing rough-in (existing layout) | Included in labor | No wet-wall changes |
| Plumbing rough-in (relocating fixtures) | Add ~$5,000 | Moving toilet, shower, or vanity to a new wall |
| Walk-in tile shower | $4,200-$8,500 | Includes pan, membrane, tile, glass |
| Tub-and-shower combo | $600-$10,000 | Huge range; specify the actual unit |
| Premade shower kit | $600-$1,800 | Budget path, not a tile shower |
| Vanity installed (stock) | $525-$1,200 | Includes sink and faucet |
| Vanity installed (mid-range) | $1,200-$2,940 | Most Waukesha County remodels land here |
| Vanity installed (premium) | $3,000-$5,000+ | Custom or semi-custom |
| Toilet installed (mid-range) | $630-$1,200 | Budget starts at $105, premium reaches $5,000 |
| Bathroom flooring | ~$12.50/sqft installed | Tile runs $10-$50/sqft installed |
| Permits (plumbing + electrical) | $100-$1,000 | Varies by municipality |
| Water damage repair (if found) | $3.75-$7/sqft | Common on 1950s-1970s Brookfield ranches |
Here's how those line items add up on a real mid-range 8x10 in Brookfield with an existing layout and no plumbing relocations: demo $1,600, walk-in tile shower $6,200, mid-range vanity installed $2,000, mid-range toilet $900, tile floor at $18 per square foot installed on 80 sq ft equals $1,440, fixtures and lighting and exhaust fan and paint bundled at roughly $1,800, permits $400, and labor across trades that isn't already embedded in the shower and vanity numbers running about $3,600. That comes to roughly $17,900. Move the toilet to a new wall and add $5,000, and now you're at $22,900, which is why the mid-range band tops out where it does.
If a bid lists "new tile" without specifying square footage and grout and thinset spec, that's not a quote. It's a placeholder. On an 8x10, tile square footage (floor plus shower walls) can range from 90 to 180 sq ft depending on shower size and whether tile runs to the ceiling. At $10-$50/sqft installed, that's a $900-$9,000 swing hiding inside one vague line item.
Why Bids Vary $10,000 on the Same 8x10 Room
This is the part every comparison shopper deserves a straight answer on. When you have a $12,000 bid and a $22,000 bid for the same room, the higher contractor is almost never gouging you. Here's what's actually happening, item by item:
Scope gaps.
The cheap bid says "new tile" but excludes subfloor repair. On a 1960s Waukesha ranch bathroom, subfloor damage under the toilet flange is the rule, not the exception, and repair runs $3.75-$7 per square foot.
Allowances vs specified fixtures.
A $500 vanity allowance sounds fine until you realize mid-range installed vanities run $1,200-$2,940. The delta comes out of your pocket as a change order.
Demo depth.
"Surface refresh" and "gut to studs" are two entirely different projects. Demo alone swings $1,000-$2,300 depending on which one you're actually getting.
Permit handling.
Some bids exclude permit fees ($100-$1,000) and the labor to pull them. That fee shows up later as a line on the final invoice.
Waterproofing method.
"We'll seal it" is not waterproofing. A Schluter Kerdi or Wedi membrane behind shower tile is. The difference is a 20-year shower versus a leak in year four. This is one of the top bathroom remodel mistakes Waukesha County homeowners make when they take the low bid.
Unforeseen conditions clause.
A complete bid names a rate for water damage repairs if found. A bare-bones bid stays silent and hits you with a change order.
Wisconsin's plumbing code under SPS 382 requires a licensed plumber, credentialed by the Wisconsin Department of Safety and Professional Services, for any fixture relocation, new drain line, or venting change. That's why the roughly $5,000 line for moving a wet-wall fixture isn't negotiable, and it's why a contractor offering to "just move the toilet quick" without a plumbing permit is putting your resale and your homeowner's insurance at risk.
Here's a specific example from our own project log. In spring 2024, John inspected a hallway bathroom in a 1962 Brookfield ranch off Calhoun Road. The homeowner had two other bids on the table, both around $13,000. Once we pulled the vanity, we found soft subfloor under the toilet flange and moisture staining across two joists from a slow supply-line drip that had been going for years. The subfloor and joist sistering repair was $4,200, disclosed in writing before we proceeded. Both of the other bids had generic "as-needed carpentry" language without a named rate, which meant the homeowner would have hit that same $4,200 as a mid-project surprise. Final invoice on that project matched the revised scope to the dollar. When the same person writes the scope and manages the job, nothing gets forgotten between the quote and the invoice.
What a Complete 8x10 Bathroom Scope Looks Like
Here's the checklist to hand every contractor bidding your job. If their written proposal doesn't address each of these points, you're not comparing prices. You're comparing guesses.
- Demo depth. Surface, partial (drywall out), or full gut to studs, named explicitly.
- Waterproofing method. Membrane brand and system (Schluter Kerdi, Wedi, Laticrete Hydro Ban), not just "sealed" or "waterproof."
- Fixture spec or realistic allowance. Either model numbers (Kohler Memoirs toilet, a specific vanity SKU) or a dollar allowance that matches actual mid-range pricing.
- Subfloor inspection and repair provision. Named rate per square foot if damage is found, with $3.75-$7/sqft being the current market.
- Plumbing rough-in. Any fixture relocations specifically called out, and licensed plumber named per SPS 382.
- Electrical. GFCI protection per NEC 210.8, dedicated circuits where code requires, and exhaust fan CFM rating (per the Home Ventilating Institute, a 50 CFM fan in an 8x10 is undersized, so plan on 80 CFM minimum).
- Tile square footage. Floor sq ft plus shower wall sq ft, with grout and thinset spec.
- Permits. Included in price and pulled by the contractor, not the homeowner.
- Cleanup and haul-away. Named as included.
- Warranty. Labor warranty length AND a separate warranty on shower waterproofing.
Bathroom - T&JAsk for this in writing before you put down a deposit. If the answer is a verbal "don't worry, we handle all that," you have your answer.
Permits and Waukesha County Code for an 8x10 Remodel
Under Wisconsin's Uniform Dwelling Code (SPS 320-325), any bathroom remodel that involves moving a plumbing fixture, adding a shower or tub, or replacing supply and drain lines requires a plumbing permit. Electrical changes (new circuits, added lighting, moved outlets) require a separate electrical permit. Permit costs on an 8x10 typically total $100-$1,000 depending on your municipality.
Each Waukesha County municipality (Brookfield, Pewaukee, Waukesha, Menomonee Falls, New Berlin, Oconomowoc) pulls its own permits and runs its own inspections. The City of Brookfield Building Inspection Department requires a licensed plumber's DSPS registration number on any plumbing permit application, with fixture relocation permits typically running $200-$400 and approval turnaround of 5-7 business days in our recent experience. A contractor telling you "we don't need a permit for this" on a job that involves any plumbing relocations is either wrong about the code or is planning to skip inspection. Both of those become your problem when you sell the house or file an insurance claim. We break down when a Wisconsin bathroom plumbing permit is required in more detail.
Timeline: How Long an 8x10 Bathroom Remodel Takes
Mid-range 8x10 bathroom remodels in Wisconsin run about 3-5 weeks of active work, and 5-7 weeks of calendar time once you factor in material lead times and inspection gaps. Full gut renovations with layout changes push toward 6-8 weeks. The sequencing usually breaks down like this: demo takes 2-3 days, rough-in plumbing and electrical plus the first inspection runs 3-5 days, waterproofing and tile takes 5-8 days, vanity and fixtures and trim and paint take another 3-5 days, and the final inspection and punch list closes out in 2-3 days.
Book lead times for reputable Waukesha County contractors currently run 4-8 weeks depending on the season, with fall and winter booking faster than spring. Any contractor promising a same-week start on a full 8x10 remodel is either between jobs for a reason, or is planning to squeeze your project between two others in a way that will show up in the finish quality.
Questions to Ask Every Contractor Before Signing
These are the questions that separate the complete bid from the bare-bones one. Ask every one to every contractor, and get the answers in writing.
Step 1
Is subfloor repair included, or billed as an extra if damage is found, and what's the named rate?
Step 2
What waterproofing membrane system are you using behind the shower tile, by brand and product line?
Step 3
Are permits included in this price, and who pulls them?
Step 4
What's your allowance for the vanity, tile, and faucet, and what happens if I pick something above the allowance?
Step 5
Who's on site every day: the owner, a lead carpenter, or a rotating sub crew?
Step 6
What's your written warranty on labor, and is there a separate warranty on the shower waterproofing?
Step 7
Are you a credited contractor in the state of Wisconsin, and can you provide your DSPS registration number?
Step 8
How do you handle change orders, and do you require written approval before work proceeds?
Step 9
What's your total exhaust fan CFM for this room, and is it vented outside or into the attic?
Step 10
Can I see the written scope before I put down a deposit?

Getting a Straight 8x10 Bathroom Quote in Waukesha County
Here's what to take with you when you open the next bid. A real 8x10 mid-range remodel in Wisconsin is $14,400-$22,400 in 2026. The bid that comes in dramatically under that number is almost always missing line items, and those missing items become change orders once demo starts. The bid that lands inside that range and shows its work (specified fixtures, named membrane, permit line, subfloor clause) is the one you can plan a budget around.

Frequently asked questions
Is $15,000 enough for an 8x10 bathroom remodel in Wisconsin?
It's enough for a mid-range refresh (new vanity, toilet, tub-shower combo or standard walk-in shower, new tile floor, updated fixtures) as long as you're not moving plumbing. The reason it's tight comes down to three layers. First, labor alone runs 40-65% of total cost in the 2026 Wisconsin market, so on $15,000 you have roughly $6,000-$9,750 in labor and $5,250-$9,000 left for materials and permits across a dozen line items. Second, mid-range vanities alone eat $1,200-$2,940 installed and a tile walk-in shower absorbs another $4,200-$8,500, which leaves very little room for surprises. Third, moving the toilet or shower to a new wall triggers roughly $5,000 in additional rough-in plus a plumbing permit, and that alone will push you into the $20K band.
Why is my bid so much higher than the other contractor's bid?
Almost always scope, not markup. The cheap bid typically excludes some combination of subfloor repair, waterproofing membrane behind tile, permit fees, realistic fixture allowances, or demo to studs. Three reasons this matters. First, the missing line items don't go away, they just become change orders once demo starts, and change-order pricing is almost always higher than bid pricing because there's no competitive pressure once you've signed. Second, waterproofing shortcuts don't fail in month one, they fail in year three or four after your labor warranty has expired, and a full shower rebuild runs $4,200-$8,500 out of pocket. Third, a bid without permits pulled means the work isn't inspected, which becomes a resale disclosure problem and an insurance problem later. On the same 80 sq ft room, a complete written scope and a bare-bones scope legitimately price $10,000 apart.
What does labor cost on an 8x10 bathroom in Waukesha County?
Labor typically runs 40-65% of total project cost, which on a mid-range 8x10 works out to roughly $6,000-$14,500. That covers the carpenter, plumber, electrician, tile-setter, and project management across 3-5 weeks of active work. Wisconsin trade rates trend higher than the national average for three reasons. State licensing requirements under DSPS mean fewer unlicensed operators bidding down the market. The compressed building season concentrates demand into eight or nine months, driving hourly rates up during peak. And Waukesha County specifically prices above rural Wisconsin counties because of density and commute costs for trade partners driving in from the Milwaukee metro.
Do I need a permit for an 8x10 bathroom remodel in Wisconsin?
If the remodel touches plumbing (moving a fixture, adding a shower, replacing supply lines) or electrical (new circuit, added lighting, moved outlets), yes. Wisconsin's Uniform Dwelling Code and municipal ordinances require it under SPS 382 for plumbing work. Total permit cost typically lands $100-$1,000. Three reasons it matters even when it feels like a hassle. First, unpermitted plumbing work becomes a disclosure item at resale and can kill a deal at inspection. Second, if a leak damages a lower floor or a neighbor's unit, unpermitted work can void your homeowner's insurance coverage. Third, an inspection is a free second set of eyes on your contractor's rough-in, which is the one time in the project you actually want a code officer looking at the pipes before drywall closes them in.
What's the difference between a budget and mid-range 8x10 remodel?
The difference is roughly $6,000-$10,000 on the same 80 sq ft room, and it lives in three places. First is the shower: a $600-$1,800 premade kit versus a $4,200-$8,500 tile walk-in. Second is the fixtures: a $525-$1,200 stock vanity versus a $1,200-$2,940 mid-range installed vanity, plus the same delta on toilet, faucet, and lighting. Third is the finish work: budget uses builder-grade paint and stock trim while mid-range includes semi-gloss enamel, upgraded trim profiles, and often accent tile. The room looks similar in real-estate photos. It doesn't feel similar in daily use, and it doesn't hold up the same over ten years.
How much does moving plumbing in an 8x10 bathroom cost?
Relocating a toilet, shower, or vanity to a different wall typically adds about $5,000 to the project for new drain lines, supply lines, venting, and sometimes concrete cutting if the bathroom sits on a slab or basement level. The wet wall is where plumbing stacks vertically, and moving a fixture away from it means running new pipes through joists or floors, plus a plumbing permit and inspection under SPS 382. On an 8x10 it's often worth it to gain a usable layout, but budget for it up front rather than as a mid-project change order. We cover a related upgrade in our tub-to-shower conversion pricing in Wisconsin guide.
How long does an 8x10 bathroom remodel take?
About 3-5 weeks of active work for a mid-range remodel, and 5-7 weeks of calendar time once you factor in material lead times, permit inspections, and small gaps between trades. Full gut renovations with layout changes push toward 6-8 weeks. Any contractor promising a two-week finish on a full remodel is either cutting corners on waterproofing (which fails within 3-5 years) or leaving out inspection wait times, which in Brookfield and Pewaukee currently run 3-7 business days per inspection.
