Bathroom remodeling services
One T and J crew runs the whole bathroom renovation: demolition, subfloor, supply and drain lines, shower pans, tile, vanities, exhaust fans, GFCI wiring, lighting and glass. Most Waukesha projects are a prewar single bath or a 1970s fiberglass tub unit. More on our bathroom remodeling service.

Showers
Pulling a cast-iron tub from a 5 by 7 prewar bath frees a 60-inch alcove for a walk-in shower. The rotted subfloor at the drain is rebuilt, the trap moves on the plumbing permit, and the pan is sloped, membraned and flood-tested before tile.
Pans
Sloped bed, bonded membrane
Walls
Porcelain, ceramic, stone
Glass
Frameless and semi-frameless

Vanities
Prewar Waukesha baths were plumbed for a wall-hung or pedestal basin, so a vanity usually means moving supply and drain lines. Quartz and cultured marble tops are templated after the cabinet is set and scribed to out-of-square plaster walls.
Cabinets
Single, double, wall-hung
Tops
Quartz, cultured marble
Basins
Undermount, integrated

Tiling
Shower tile goes over cement board or a bonded membrane, never bare plaster. Prewar joists are checked for deflection before large-format porcelain, and radiant mats can go in the setting bed for Wisconsin winters.
Floors
Porcelain, ceramic, vinyl plank
Walls
Subway, large format, mosaic
Heat
Radiant mats in the bed

Full rebuild
Studs-out is the one chance to replace galvanized supply, lead bends and an unvented cast-iron stack instead of tiling over them. Everything is rebuilt and inspected before walls close.
Depth
Framing and subfloor
Services
Supply, waste, vent, wiring
Filings
Plumbing rough-in inspection

Accessibility
Curbless entries, comfort-height toilets, handheld showers and benches. Many prewar Waukesha homes have their only bath upstairs, so a first-floor accessible bath often means an addition. Blocking behind the tile takes grab bars any time.
Entry
Curbless and low-threshold
Support
Blocking behind the tile
Fixtures
Comfort height, handheld, bench

Fit-out
Many prewar Waukesha baths vent only through a window, so paint peels and mildew spots the ceiling each winter. T and J ducts a room-sized fan outdoors, adds GFCI protection and wet-rated shower lighting.
Ventilation
Ducted out, sized to the room
Lights
Vanity, recessed, wet-rated
Wiring
GFCI on its own permit

Before you price it
Three things set the scope: the age of the house, how many baths it has, and whether plumbing moves. Waukesha spans the 1850 to 1932 houses of the College Avenue Historic District near Carroll University and postwar ranches and duplexes across 53186, 53188 and 53189. T and J prices all three into one fixed quote. See what older Waukesha walls hide.
Housing age
Pre-1980
Just over half of Waukesha homes, so galvanized supply, cast-iron drains and window-only ventilation are common.
Out of service
1–5 weeks
Tile, glass and fixtures arrive before demolition, so a one-bath house loses the room only while the crew works.
Plumbing permit
Licensed only
The City of Waukesha issues plumbing permits to licensed plumbers only. The inspector signs off rough-in before walls close.
What it costs
Waukesha bathroom remodels run $12,000 for a surface update to $45,000 and up for a full rebuild, with most T and J jobs at $20,000 to $32,000. Galvanized supply and unvented drains push prewar baths higher. One fixed written price, no deposit. See the Waukesha bathroom cost guide.

Surfaces and vanities
Waukesha’s 2023 switch to softer Lake Michigan water means less scale on shower glass, grout and faucets. These are the tile, countertop and vanity options T and J installs in small, high-use bathrooms.
Low absorption, the default on shower walls and floors.
Lighter and cheaper on surrounds and wainscot.
Marble and granite looks, resealed every 6 to 12 months.
Seamless panels with no grout to scrub.
Non-porous, never needs sealing.
Cast top with the bowl built in, no seam.
Classic door style for prewar and postwar Waukesha homes.
Buys back floor space in a small prewar bath.
Wet-area surfaces compared
| Material | Water resistance | Fits a small prewar bath | Upkeep | Typical Waukesha use |
|---|---|---|---|---|
| Porcelain tile Most chosen | Very low absorption | Large format needs a flat floor | Seal grout only | Shower walls and floors |
| Ceramic tile | Low absorption on walls | Small format forgives old plaster | Seal grout only | Tub surrounds and wainscot |
| Solid surface | Non-porous panels | Seamless in a tight corner | Wipe clean, no grout | Fast single-bath turnarounds |
| Cultured marble | Non-porous, cast | Bowl and top in one piece | Avoid abrasives | Rental and duplex vanities |
| Quartz top | Non-porous slab | Scribes to a crooked wall | Never sealed | Vanities in daily-use baths |
| Natural stone | Porous, needs sealer | Heavy on old joists | Seal every 6 to 12 months | Larger postwar primary baths |
Bathroom sizes
Prewar Waukesha baths are often 5 by 7 feet or smaller. Code clearances set the layout: 15 inches from the toilet centerline to any side wall, 21 inches clear in front, and a shower at least 30 by 30 inches. More small bathroom layouts for Waukesha County homes.

Common in prewar houses. Usually a tub-to-shower conversion and a wall-hung basin to keep floor space.

The standard single bath. Tub on the short wall, basin opposite, little room to move a fixture without opening the floor.

An extra foot, usually spent on a 60 inch vanity or a longer walk-in shower with a bench.

Sloped ceilings over the fixtures. Head height at the shower decides the layout before anything else.

Tight footprint, shared stack, and a turnaround window between tenants.
Waukesha permits
Yes, once plumbing moves, circuits are added or a wall opens. Swapping a vanity, toilet or tile in place usually needs no permit.
The City of Waukesha issues plumbing permits to licensed plumbers only, never to homeowners, and the inspector checks the piping at rough-in before walls close. Applications run through the City’s eTRAKiT portal with dimensioned drawings, reviewed by the Community Development Department at City Hall, 201 Delafield Street, (262) 524-3750. T and J prepares the drawings, coordinates the filing and meets the inspector on site. See when Wisconsin requires a bathroom plumbing permit.

First visit
John Karampetsos measures the room and checks the stack, supply and subfloor, because in a prewar Waukesha house those set the scope more than the layout does.
No charge, at your house
Weeks 1 to 2
Tile, glass, vanity and valve trim are chosen together, since the valve sets the wall layout.
No money down
Review time
The plumbing application goes in with the drawings, and tile and fixtures are ordered while it is reviewed.
Handled by T and J
Weeks 1 to 3
The room comes out to studs, rot at the flange is corrected, galvanized supply is replaced, and the inspector signs the rough-in before anything closes.
In-house crew
Last weeks
The pan is sloped, the membrane bonded and flood-tested, then tile, vanity and fixtures go in and the glass is templated to the finished tile.

Common questions
Questions about your own bathroom remodel? Call T and J at (262) 352-9525.
The branches inside the bathroom walls, yes. Galvanized steel corrodes from the inside, so low pressure and rust-tinted water get worse with age, and reopening new tile later to reach it costs far more than replacing it now. Runs elsewhere in the house can be assessed and priced on their own, and home inspectors routinely flag galvanized supply when a house is sold.
Often not at the old setting. City water has come from Lake Michigan since 2023 and is about 60 percent softer than the groundwater it replaced, and the City required softeners still in use to be adjusted for the softer supply by January 1, 2025, to cut chloride discharge. If yours hasn’t been reset, have it done before the new valves and glass go in.
It usually surfaces at sale. The Wisconsin Real Estate Condition Report asks sellers whether they know of remodeling or repairs to the structure or mechanical systems done without required permits, and a buyer’s inspector looks for it. The City can also require an after-the-fact permit, which may mean opening finished walls so the inspector can see the piping.
Porcelain floor tile, a solid-surface or acrylic shower base, a quartz or cultured-marble top with an integral bowl, pressure-balancing valves with standard cartridges and sealed LED fixtures. The goal is surfaces a tenant can’t easily damage and parts a plumber can replace off the shelf. In a Waukesha duplex, matching both units’ fixtures keeps spare parts simple.
