Bathroom Remodeling That Moves the Tub, the Toilet or the Walls
A remodel changes the bathroom’s layout: the corner garden tub comes out for a walk-in shower, the toilet moves to its own room, a wall shifts to borrow space from a closet. On a slab foundation each of those moves means concrete work, so the drain lines get planned before the tile does.

In Houston primary baths, the corner garden tub is the usual target. Builders put them in for years, most families stopped using them, and they eat a big piece of floor. We have torn one out for an accessible conversion, and the sequence holds for any tub-to-shower job: demolish the tub and its deck, open the slab, relocate the drain to where the new shower drain goes, build a proper shower pan or a curbless slope, and frame the new walls. Moving a toilet works the same way, because its flange sits on a drain buried in the concrete.
Waterproofing is the part nobody sees and the cause of most callbacks. A shower needs a continuous waterproof layer behind the tile, either a liquid-applied membrane or a sheet membrane over cement board, sealed at every seam, corner and valve. We flood-test the pan before tile goes down. Niches, benches and glass all need blocking framed in before the walls close. Outlets and lights near water need GFCI protection, and a vanity moving to a new wall means new supply lines and a new drain.
Houston humidity makes ventilation more than a box to check. The fan has to vent outdoors through the roof or a wall, sized to the room, on a timer or humidity sensor so it runs long enough to dry things out. Fans that dump into the attic feed mold on the roof deck. If the bathroom sits on an exterior wall, we look for old leaks at the window too. Remodels that move plumbing usually need a permit through the county or the city, depending on where you live.
Most homes around Houston sit on a slab, so moving a sink or a toilet means cutting concrete, and that changes the price and the timeline. We say that up front. We also check for the things that hide behind drywall here: old water damage, termite trails and attic ductwork that has been crushed.
If the layout is fine and the tile and vanity are just tired, a bathroom renovation in the same footprint gets you most of the look for much less work.
When bathroom remodeling makes sense
How we decide, written down so you can hold us to it.
- The tub nobody uses takes up the floor you want for a bigger shower.
- The toilet, vanity or shower sits where it makes the room awkward, and fixing that means moving drains.
- You want to borrow space from a closet or linen cabinet to make the bathroom bigger.
And when it does not
- If you’re planning for a wheelchair or a walker, ask about our ADA work, because clearances and grab bar blocking change the whole plan.
- If there’s a soft spot by the toilet or a stain on the ceiling below, the first job is finding the leak, and we’ll do that before anyone talks about tile.
How we run it
- I
Plan the drains
We measure, decide where every fixture lands, and map the slab cuts and new drain runs.
- II
Demolition and slab work
The old room comes out to the studs, the slab is cut and trenched, and new drains are set and inspected.
- III
Framing, waterproofing, rough-in
New walls, blocking, membrane and supply lines go in, and the shower pan gets its flood test.
- IV
Tile, fixtures, glass
Tile, vanity, toilet and fixtures are installed, glass is measured after the tile is set, and the exhaust fan is tested.
What we ask before we price it
- What is not working about the room the way it is now?
- Are there finishes you already have in mind, or should we bring samples?
- Has the plumbing under the slab ever been repaired?
- Is there a date you are working toward, like a move-in or a family event?
- Which finishes are you set on, and which are you open about?
Can you replace my garden tub with a walk-in shower?
Yes. The tub and deck come out, the drain gets moved in the slab to the new shower location, and the shower is built on a properly waterproofed pan.
How long does a bathroom remodel take?
Longer than a renovation, because of the slab work and inspections. The drain inspection and the waterproofing cure time set the pace, and your schedule comes with the scope.
Is a curbless shower possible on a slab?
Often. The slab gets recessed or the floor gets built up so the shower floor slopes to the drain without a curb. It takes more planning, and we check the slab first.
Do I need a permit to move plumbing?
Usually, yes. Relocating drains and supply lines typically needs a plumbing permit and inspection. Unincorporated areas go through the county, and cities run their own permit office.
Why does the fan matter so much?
Houston air is already humid, and a shower adds a lot more. A fan that vents outside and runs long enough is what keeps paint from peeling and mold from starting.
Can we use another bathroom during the work?
If you have one, yes. If this is your only bathroom, tell us at the first visit, because we schedule the job very differently.
