Tub-to-Shower Conversions in Collin County

The corner garden tub is the most reliably wasted square footage in a Collin County primary bath. Builders dropped them into thousands of 1990s and 2000s homes across Allen, Plano, Frisco, and McKinney as a selling feature, and a generation of owners has filled them maybe twice — while showering in the cramped stall beside it. Converting that tub to a real walk-in shower is one of the most-requested moves in a bathroom remodel, and like most bathroom work, the honest version is a small plumbing-and-waterproofing build, not a swap you can finish over a weekend.

Moving the drain is the part people underestimate

A tub and a shower drain in different places, and that single fact drives the whole job. A tub drains at one end of its footprint; a shower drains from the center, or along a linear slot against a wall. So a genuine conversion almost always means relocating the drain — and on these slab-on-grade homes the drain lines live inside the concrete, which means cutting the slab, re-routing the pipe, and re-pouring, with a licensed plumber filing a plumbing permit and passing a rough-in inspection before anything closes. That slab work is the difference between a shower that drains correctly and one that pools, and it's precisely the step a tub-shaped drop-in shower kit is designed to avoid — at the cost of a floor that never slopes the way it should.

Valve, supply, and the anti-scald code

A tub filler and a shower valve are not the same fixture at the same height. Converting means opening the wall to rework the supply, set a proper shower valve at a usable height, and run the riser to the head — and code expects that new valve to be a pressure-balancing or thermostatic mixing valve, the anti-scald protection that keeps a flushed toilet elsewhere in the house from sending a spike of hot water at whoever's in the shower. There's no way to do this behind an unopened wall, which is why a real conversion is built from the backer board out, not skinned over the old surround.

The waterproofed wall behind the tile

With the plumbing reworked, the shower becomes the same waterproofing assembly every tile shower is: a sloped pan, a continuous membrane sealing the pan and walls, backer board instead of drywall in the wet zone, every seam sealed and flood-tested before tile. This is the layer that decides whether the conversion lasts, and the one low-bid jobs quietly skip — the tile looks right, the assembly behind it was never built to hold water. A niche, a bench, and frameless or framed glass are the visible payoff riding on top of a box that has to stay watertight for decades. It's the same standard we hold on every job in McKinney or in Frisco, where the housing stock and the Blackland Prairie clay under it are the same story.

Keep a tub somewhere in the house

There's one resale note worth saying plainly: don't take the last tub out of the home. A house with zero bathtubs tends to put off buyers with young children, and appraisers and agents still treat at least one tub as an expectation in a family home. The right move is usually to convert the underused primary garden tub — the one nobody fills — while keeping a tub in a secondary or hall bath, so the household gets the shower it actually uses without narrowing the pool of future buyers. It's general guidance, not a guarantee about any one sale, but it's the pattern that protects the home's value. Our broader bathroom remodeling work and the Collin County permit guide both come back to the same idea: plan the whole house, not just the one room.

Common questions

Do you always have to move the drain to convert a tub to a shower? Almost always, yes. Tub drains sit at one end of the footprint and shower drains run from the center or a linear slot, so the drain location has to change — and on a slab foundation that means cutting concrete, re-routing pipe, and pulling a plumbing permit. A conversion that claims to skip this is usually a liner or drop-in unit sitting over a drain that isn't where a shower needs it.

Can a tub-to-shower conversion be done without opening the wall? Not a real one. Reworking the valve and supply and building a waterproofed tile shower both require the wall open to the studs — the shower is built from backer board and a sealed membrane outward, and the code-required anti-scald valve lives inside that wall. Products that promise an unopened-wall swap are skinning over the old surround, not building a shower to last.

Should I convert my only bathtub to a shower? Generally, no. Keeping at least one tub in the home — usually a secondary or hall bath — protects resale, since buyers with young children and many appraisers still expect one. The common and safer move is to convert the underused primary garden tub while leaving a tub elsewhere in the house.

Does converting the tub add or hurt the home's value? Turning a dated, never-used garden tub into a well-built walk-in shower generally appeals to buyers, provided the home keeps a tub somewhere. It isn't a guaranteed dollar return — that depends on the buyer and the rest of the house — but a code-built, properly waterproofed shower reads as an upgrade, while a leaking or obviously cut-rate conversion reads as a liability.
