Bathroom Remodeling

From a same-footprint refresh to a full gut — waterproofed by our own crew.

Bathrooms pack more trades into fewer square feet than any room in the house — plumbing, electrical, waterproofing, tile, cabinetry, and glass — which is exactly why our in-house crew shines here. We handle the rough-in, the waterproofing, the tile, and the vanity ourselves, so nothing waits on a sub.

Every bathroom starts with a complimentary 3D model so you approve the layout, tile, and fixtures before demolition. We tell you plainly what moving a drain costs versus keeping the footprint, build showers on a proper waterproofing system before a single tile goes on, and fabricate vanity tops through our cabinetry shop.

What's included

  • Complimentary 3D design model

    A complimentary 3D model of the new bathroom — layout, tile, vanity and fixtures — approved before demolition.

  • Layout, fixture, and structural assessment

    We tell you what it costs to move a toilet or shower drain versus keep the footprint, and whether a wall or window change needs engineering.

  • Plumbing and electrical rough-in (in-house)

    Our own plumbers and electricians run the rough-in: new drains and supplies, a dedicated circuit for a heated floor or bidet seat, lighting and ventilation.

  • Vanities and quartz/granite tops

    Vanities built to fit and quartz or granite tops fabricated through our cabinetry shop.

  • Shower waterproofing, pans, and tile

    Shower pans, curbless showers and tub surrounds built on a proper waterproofing system before a single tile goes on, with full mortar coverage behind the tile.

  • Fixtures, glass, lighting, and finish

    Tub or shower, toilet, faucets, glass, lighting, mirror, paint and accessories, then a walkthrough before we call it done.

How it works

  1. 1
    Free advice visit

    We measure the room, look at the plumbing and ventilation and talk refresh versus full gut — then leave you a scoped range.

  2. 2
    Complimentary 3D model

    The new bathroom on your actual room, so tile, vanity and fixture choices are made before demolition.

  3. 3
    Selections and permits

    Fixtures, tile and vanity selected and ordered; plumbing and electrical permits pulled, plus a building permit if the footprint or structure changes.

  4. 4
    Demolition and rough-in

    Old finishes out, framing corrected, plumbing and electrical rough-ins inspected.

  5. 5
    Waterproofing, tile and finishes

    Pan and walls waterproofed, tile set and grouted, vanity, counters, fixtures, glass and lighting installed.

  6. 6
    Final walkthrough

    Every fixture run, every seal checked, with you.

The same ten-step process runs every project we build — see how we work.

What it costs

The range is per bathroom and steps with the room — powder room, hall bath or primary suite — then scope and fixtures move it: a refresh in the same footprint runs about 15% less than a full renovation, moving one fixture adds about 6% and relocating the layout about 12%. A tub-to-shower conversion adds about 5%, tile to the ceiling about 4% and an electric heated floor about 3%.

Timeline

  1. Design and selections

    3D model, then fixtures, tile and vanity chosen and ordered before anything comes out.

  2. Demolition and rough-in

    Old surfaces and fixtures out, framing and subfloor corrected, plumbing and electrical rough-ins inspected.

  3. Waterproofing and tile

    Shower pan and walls waterproofed and flood-tested where required, then tile set and grouted.

  4. Fixtures and finishes

    Vanity and top, toilet, tub or shower fixtures, glass, lighting, paint and accessories.

  5. Walkthrough

    The room is out of service from demolition until the tile is grouted and the fixtures are set; keeping the fixtures where they are is the shortest path.

Permits and codes

Plumbing and electrical permits at minimum, plus a building permit when the footprint or structure changes — a new window, a moved wall or a skylight. A larger water heater or a dedicated circuit for a heated floor adds to the electrical or plumbing scope.

We pull the permits, handle any structural work through our engineering and permitting team and schedule the rough-in and final inspections so the room is closed up and tiled without waiting.

Questions, answered

If the waterproofing and plumbing are sound, a refresh — new fixtures and surfaces in the same footprint — runs about 15% below a full renovation. If the pan leaks, the walls are soft or you want a different layout, a full gut to the studs is the honest answer; our Missoula bathroom was taken to the studs, while our Billings bathroom was rebuilt in place without moving a wall.

A continuous waterproofing system behind the tile — pan, curb or curbless slope, walls and corners — installed before any tile goes on, with full mortar coverage behind the tile. Tile is the finish, not the waterproofing, and that distinction is what keeps a shower dry for decades.

Yes — it adds about 5% to the range for the new pan, drain and glass, and a curbless entry like the one in our Missoula project is an option. Keep at least one tub in the house if you plan to sell.

Yes. An electric heated floor adds about 3% in our estimate tool and needs a dedicated circuit, which our electricians run during the rough-in; our Missoula remodel used electric in-floor heat under the tile.

Yes — roll-in or curbless showers, grab bars on proper blocking, wider doorways, comfort-height toilets and lever hardware. For licensed care settings see our adult family home modifications page, which covers Washington DSHS requirements.

From demolition until the tile is grouted and the fixtures are set. We give you the schedule at the free advice visit; keeping the fixtures where they are and having tile and fixtures on site before demo are the two things that shorten it.

Plumbing and electrical permits at minimum, and a building permit when the footprint or structure changes. We pull them.
