Thompsons 77481 sits about 20 miles from our shop, and double vanity installation is work we do there regularly.
Not every tired double vanity needs replacing. A cabinet with sound plywood boxes and a dated top is a different problem from a cabinet whose base has swollen from a decade of slow drips. The trouble is that the failing part is usually the one you cannot see: the deck under the bowls, the toe kick, the supply stops behind the doors. Around Houston, humidity and hard water quietly do most of the damage, and slab movement handles the rest. This is how the decision gets made in practice, part by part, and what tips a job from refinishing and re-topping into a full replacement.
What we see in Thompsons
Thompsons is a very small Fort Bend County town near the Brazos south of Sugar Land, and there is no typical house here to describe honestly. It is rural — acreage, a limited number of homes, a wide spread of construction dates and building types, and a reasonable likelihood of private well and septic rather than city utilities. What that means in practice is that we approach projects here property by property rather than by neighborhood pattern. Water hardness, septic capacity if you are adding a bathroom rather than replacing one, service size at the panel, and how the structure is actually framed are all things we confirm on site instead of assuming. Elevation and floodplain status vary along the river corridor and should be checked for the specific parcel. The Gulf Coast constants still apply: expansive clay moves seasonally, humidity stays high year-round, and the details that manage both are what keep a remodel looking right in year five.
What we actually do
Assessment comes first and it is physical. We empty the cabinet and look at the deck under both bowls for staining, delamination and soft spots, then the toe kick and the back of the base where floor water collects. Doors and drawer boxes get checked for square, hinge condition and whether the boxes are dovetailed plywood or stapled particleboard. Then plumbing: supply stops operated by hand to see whether they turn and hold, tailpieces and traps checked for corrosion, and the drain material identified, since cast iron and galvanised steel behave very differently from PVC. We measure cabinet height, because older units sit noticeably lower than current ones and raising the height changes drain and supply stub positions. The top gets inspected for cracks at the cutouts, failed seams and, on cultured marble, gel coat wear and yellowing. From there the paths separate: hardware, faucets and refinishing only; keeping the cabinet and fitting a new top with new bowls; or removing everything and starting from the wall.
Choosing materials
What can be reused matters more than what is new. Plywood cabinet boxes with sound finishes take paint or refinishing well and can carry a new top for years. Particleboard boxes that have been wet cannot. Cultured marble tops with integral bowls cannot accept undermount sinks, so wanting undermount bowls means a new top regardless of the cabinet’s condition. Existing stone tops rarely survive removal intact, so anyone planning to reuse one should assume it will not. Tile backsplashes bonded to the old deck usually come off with it, which means backsplash work is part of any re-top. On the new side, engineered quartz is forgiving in a bathroom, granite is durable and varies by slab, and marble etches from routine products. Faucets should have solid brass bodies and ceramic disc cartridges, in a PVD finish if hard water bothers you. Supply stops get replaced as a matter of course, in quarter-turn form rather than the old multi-turn type.
Why this is different on the Gulf Coast
Three local conditions decide most of these calls. Humidity means any particleboard box that has been wet stays damaged, since it swells and does not dry back, so a swollen deck or toe kick effectively ends the repair conversation. Hard water is the second: scale wrecks faucet cartridges and aerators long before the finish fails, and it etches cheaper chrome, which is why a faucet swap alone often transforms how a vanity feels to use. Third is slab movement. On expansive clay, floors shift seasonally, and a long double cabinet that has racked will not accept a new stone top without shimming and re-levelling first, because stone will not bridge an uneven bearing surface indefinitely. In older inner-Houston houses there is a fourth: cast-iron drains and galvanised supply lines behind the wall. If those are corroded, the sensible time to address them is while the vanity is out, not two years later.
Where these jobs fail
The common error is re-topping a cabinet that is not level or is quietly failing. Stone set on a racked or soft base bears unevenly, and cracks appear at the sink cutouts months later, which people then blame on the material. Second is reusing corroded angle stops because they happen to be closed at the moment. They seize, they weep, and replacing them later means opening finished work. Third is keeping an old faucet on a new top, where a worn cartridge and scaled aerator undercut everything you just paid for, and the holes may not match the new drilling anyway. Fourth is assuming the old top lifts off cleanly. Stone and tile decks are usually adhered and come out in pieces, taking backsplash and sometimes drywall with them, so plan wall repair into the scope. Finally, changing to a taller cabinet without checking the existing drain stub height leaves the trap arm in the wrong place, and on a slab that is not a trivial correction.
What to expect
We inspect before quoting, because the deciding evidence is inside the cabinet and behind the doors, not in a photograph. You get the options priced separately, so the difference between refinishing, re-topping and replacing is visible rather than bundled. If a re-top is viable, the cabinet is levelled and reinforced before templating, and the template is taken from the cabinet as it will sit. If replacement is the call, plumbing and electrical are addressed while the wall is open, then the sequence runs cabinet, template, fabrication wait, top set, trim, caulk and cure.

What moves the price
The size of the job is set by how far down the stack the failure goes. Hardware, faucets and refinishing is mostly labour. A re-top adds fabrication, bowls and backsplash repair, and its price moves with material, edge profile and cutout count. A full replacement adds demolition, disposal, cabinet cost, wall and floor repair where the old footprint differed, and any plumbing correction. Plumbing is the big swing: in-wall changes are routine, while relocating a drain in a slab means saw-cutting and concrete restoration. Older houses add work when cast iron or galvanised piping is found in poor condition. Electrical adds cost when a bathroom lacks proper receptacle protection or the house has aluminium branch wiring requiring rated terminations. Permit requirements differ between the City of Houston and unincorporated Harris and Fort Bend County.
Common questions
When is keeping the cabinet and replacing the top the right call?
When the boxes are plywood, the deck under the bowls is dry and solid, the doors and drawers still work, and the layout and height suit you. That combination is common in better-built cabinets. If the deck is swollen, the toe kick is soft, or you want a different height, the savings evaporate quickly.
Can I go from one sink to two without replacing the cabinet?
Only if the cabinet is wide enough for two bowls with workable spacing and the interior can accommodate a second drain. The real constraint is usually plumbing, since the second lavatory needs a drain and venting arrangement, and on a slab the practical approach is running it inside the wall to the existing outlet.
Will my existing countertop survive removal?
Assume it will not. Stone and tile decks are typically adhered to the cabinet and to the wall, and they come away in pieces more often than not. If reuse genuinely matters, say so before demolition so removal can be attempted carefully, but nobody can promise it will come out whole.
Should the supply lines and stops be replaced while it is open?
Yes, in almost every case. Access is the expensive part and it is already paid for. Quarter-turn stops and new supply connectors are inexpensive compared with opening a finished vanity later, and in older houses this is often the moment corroded galvanised piping is found and dealt with sensibly.
