We handle double vanity installation across 77002 in Houston, roughly 17 miles from our Energy Corridor base.
A double vanity install in a 1972 Memorial-area bathroom and one in a 2008 Cypress bathroom involve the same cabinet and completely different risk. The older house may have galvanized supply lines, a cast iron drain, a vanity that was scribed to a wall that has since moved, and drywall behind it that has been quietly damp for years. The newer house probably has PVC drains and clean copper or PEX supplies, but it may sit on a post-tension slab that nobody should cut, and it likely has a builder vanity with a particleboard box that has already begun to swell under the sink. Different problems, both worth knowing before demo day.
What the work involves
In the older home we open things up carefully and look. Supply lines get identified; galvanized pipe from that era corrodes internally and restricts flow, and if it is present the conversation about replacing the visible runs happens now while the wall is open. Angle stops from that period are usually multi-turn valves that no longer seal, and they get replaced regardless. Cast iron drain lines get inspected where visible for scaling and thin walls.
Drywall behind the old vanity is frequently stained or soft, and it comes out. Blocking often has to be added, since older framing does not always land where a modern cabinet wants to fasten.
In the newer home the work moves faster to the cabinet itself. We check whether the existing rough-in matches the new layout, then reroute inside the wall as needed. Post-tension slabs get treated as untouchable unless a scan and an engineered approach say otherwise.
Both converge at the same finish: cabinet shimmed level and plumb, scribed to the wall, countertop templated on the set cabinet, undermount bowls, new stops and supplies, leak test, backsplash, caulk, mirrors, lighting.
Materials and specification
Material selection follows the house. In older baths, cabinets often need to be built or heavily scribed to fit walls that are neither plumb nor straight, and plywood construction with a moisture-tolerant finish is worth the difference. Supply piping gets upgraded at the stub-out while it is open, and quarter-turn stops replace the old multi-turn ones. Where aluminium branch wiring is present, any device or splice gets terminations rated for that conductor rather than ordinary connectors. In newer baths the cabinet is often serviceable and the failure is the top, so the choice is between engineered quartz, granite, porcelain slab or a solid surface with integrated bowls. Quartz is predictable and forgiving; granite varies by slab; marble etches from ordinary bathroom products. Cultured marble is inexpensive and seamless but the gel coat wears and yellows, which is why so many are being replaced now. In both houses, faucets get solid brass bodies, ceramic disc cartridges and a PVD finish for hard water.
Building for Gulf Coast conditions
The older Houston bathroom carries decades of humidity history. Original vanities in 1960s and 1970s homes often used particleboard or thin plywood with a laminate skin, and after fifty years of high ambient moisture plus at least one supply weep, the sink base is usually degraded. That is frequently what prompts the call. The wall behind it may have been damp long enough to affect the drywall and sometimes the baseboard.
Slab movement shows here too. A vanity installed in 1972 was scribed to a floor that has gone through fifty years of clay swelling and shrinking with our wet and dry cycles, so the wall and floor you measure today are not the ones the original cabinet was fit to. Long runs almost always need shimming.
Newer suburban homes have their own version. Builder-grade vanities were installed fast, and gaps at the wall get filled with caulk that eventually opens. Post-tension slabs, common in Houston-area construction from roughly the 1980s onward, mean drain relocation stays in the wall. And hard water has already left its mark on original faucets, which is usually why they are being replaced along with everything else.
Working in Houston
Houston is not one housing stock, so it is not one kind of remodel. In the Heights and Woodland Heights you are often working on 1910s–1930s wood-frame homes on pier-and-beam, where leveling, sill and joist repair, and original wiring long past its service life come before anything cosmetic — and where a home in a designated historic district brings design review with it. Montrose, Oak Forest and Garden Oaks add mid-century layers. Meyerland, Westbury, Braeswood and Sharpstown are largely 1950s–60s slab ranch: cast iron drains near the end of their life, galvanized supply, single-pane windows, popcorn ceilings that should be tested before they are disturbed. Memorial and Alief lean 1970s–80s, which brings aluminum branch wiring and polybutylene supply into the conversation. West of Beltway 8 you are usually in 2000s and 2010s construction, where the job is upgrade rather than repair. Houston has no zoning, but plumbing, electrical and structural work is permitted, and deed restrictions still govern a great deal.
What goes wrong, and how it is avoided
The classic sequencing error is ordering or fabricating the top before the cabinet is set and levelled. Slab-borne floors are rarely flat, and a top cut to a drawing rather than to the installed cabinet will show gaps at the wall or bear unevenly and crack later. Nearly as common is assuming the existing angle stops will hold. Old chrome stops with rubber washers seize and weep, so a plan for shutting the house main should exist before the wrench comes out, and stops get replaced while access is open. Skipping dust control is a false economy, because cutting tile backsplash and drilling stone throws fine particulate that migrates through the whole house. In pre-1980 houses, ceiling texture gets tested before anything is disturbed. Booking the electrician after the top is set means somebody works around new stone. And leaving the water off overnight without warning the household turns a manageable inconvenience into a bad week.
What drives the cost
In older homes the cost lives in what you find. Galvanized supply, corroded stops, damaged drywall, missing blocking, an unlevel floor, and sometimes a cast iron drain that has scaled down. None of it is exotic, all of it is real labor, and it is why an honest quote on a 1970s bathroom includes clearly stated allowances rather than a flat number that pretends nothing will be discovered.
In newer homes the cost is more predictable and shifts to the cabinet and top you select, plus any electrical you add at the vanity.
Common to both: whether the drains move and how far, whether a stock cabinet width fits or the wall needs a custom size, and countertop material and fabrication.
Finish work that comes along for the ride, meaning flooring under the old footprint, new mirrors, lighting, and a repainted wall, is often the difference between a vanity swap and a bathroom that looks genuinely renovated.
How we work
We inspect before quoting, including under the existing vanity and behind an access point where one exists. In an older home we tell you plainly which conditions we can see and which ones can only be confirmed after demo, and we handle those as written allowances.
Demo and discovery happen early so surprises surface before your countertop is fabricated, not after. Plumbing rough, wall repair, and blocking follow. Cabinet gets set, leveled, and scribed. Then countertop template, fabrication, install, connection, and leak test.
Backsplash, caulk, mirrors, and lighting finish the room, and we walk it with you under good light.
We confirm permitting for your address, since the City of Houston and unincorporated Harris and Fort Bend County handle plumbing and electrical work differently. If you want an inspection before you plan a budget, call (281) 235-6971.
Common questions
My 1970s house has galvanized supply lines. Do they have to be replaced?
Not necessarily as part of a vanity job, but it is the cheapest moment to replace the accessible portion. Galvanized pipe corrodes from the inside and restricts flow over decades, which is often why a fixture runs weak. Replacing the exposed run in an open wall is straightforward. A whole-house repipe is a separate decision with its own scope.
What is a post-tension slab and why does it matter here?
It is a concrete slab reinforced with steel tendons held under tension, common in Houston-area homes built from roughly the 1980s onward. Cutting or core drilling into one without locating the tendons can sever them, which is a serious structural problem. It is the main reason we solve drain relocation inside the wall cavity whenever it is possible to do so.
Why is my bathroom floor not level?
Slab-on-grade over expansive Gulf Coast clay. The soil swells when wet and shrinks in drought, and slabs respond over years. Most Houston bathrooms are out of level by an amount you would never notice walking on them but that shows immediately across an eight-foot cabinet run. Shimming and scribing handle it. It is normal here, not a defect on its own.
Should I replace the flooring at the same time?
If the old vanity footprint is larger or smaller than the new one, you will have an unfinished area, so it usually forces the question. Running new flooring wall to wall while the cabinet is out is far easier than working around it later. If the existing floor is in good shape and the footprint matches closely, patching can work.
