Bathroom Remodeling

Bathroom Vanities in Dallas, TX

Bathroom vanity installation in Dallas starts with measurements most people never think about: where the drain leaves the wall, how high the supply lines sit and whether the framing in an older home can hold the weight. We design, build and install custom and ready-made vanities with stone tops as part of our bathroom remodeling work.

Vanities take more abuse than they get credit for: water splashed across the top every morning, damp towels in the cabinet, and a drain trap that eventually drips. A good replacement fixes the storage and the looks, and it also gets the plumbing and support right.

What Bathroom Vanity Installation in Dallas Includes

A vanity replacement with us covers more than setting a cabinet:

  • Removal of the old vanity and top, with water shut off and the lines capped.
  • New shutoff valves and supply lines, plus a new trap when the old one is corroded or the wrong size.
  • The cabinet itself, custom built or ready-made, leveled and fastened to the wall framing.
  • Countertop and sinks, in quartz, granite or marble, with undermount, integrated or vessel sinks.
  • Faucets, backsplash, mirror and lighting, including relocated sconces or outlets when the layout changes.

We also check what the vanity sits on. If the floor under the old cabinet is soft from a past leak, it is repaired before the new one goes in, and the tile edge is planned so a new footprint does not leave a gap. Wall-hung vanities get blocking in the wall first.

When Bathroom Cabinets Need Replacing, Not Repainting

A vanity needs replacing when the cabinet box, not just the finish, has failed. Swollen or peeling particleboard at the toe kick and under the sink, a cabinet floor stained by a slow drip, doors that no longer close square and a top that rocks or has pulled away from the wall are the usual signs. Paint fixes none of them.

Dallas homes add their own causes. Many 1970s to 1990s houses still have one-piece cultured-marble tops whose surface crazes around the drain, and slab movement on expansive clay can open a gap between the backsplash and the wall. If you also want a second sink, more drawers or a taller counter, a new vanity solves the storage problem and the wear at once.

Custom Bathroom Vanity or a Ready-Made Cabinet?

Ready-made vanities come in standard widths, typically in 6-inch steps, with a top already fitted. They work well when the wall happens to match a standard size and the room has no odd angles.

A custom bathroom vanity is built to your wall, your height and your storage. That matters in older Dallas homes where walls are rarely square, in primary baths where two people need their own drawers, and when you want the vanity to match kitchen cabinetry. Since we design and build cabinets for kitchens, the same drawings, door styles and finishes can carry into the bath.

Double Vanity Installation: Space and Plumbing Checks

Before a double vanity is ordered, three things are confirmed. First, width: about 60 inches is a practical minimum for two sinks, and 72 inches gives each person real counter space. Second, the drain: a second sink can often tie into the existing wall drain, but distance and venting have to suit the plumbing code. Third, the supply lines: a second set of hot and cold lines is run inside the wall.

In Texas, a plumber licensed by the Texas State Board of Plumbing Examiners must do that work, and adding lines in the wall normally needs a permit. In the City of Dallas only a registered contractor can pull it, and the rough plumbing is inspected before the drywall closes. Moved sconces or a new outlet go to a TDLR-licensed electrician, and Richardson, Plano and University Park each run their own inspections.

Are Floating Vanities Strong Enough for a Stone Top?

Yes, with the right preparation. A floating vanity hangs from the wall, so the cabinet, top, sink and anything leaning on it are carried by the fasteners and the framing behind them. We open the wall and install solid wood blocking between the studs, then anchor the cabinet into it.

The plumbing changes too. The drain and supplies must sit high enough to be hidden inside the cabinet rather than showing below it. A floating vanity also leaves the floor exposed underneath, so the tile has to run under it. In a tight room that open floor makes the space feel larger, so a floating vanity is a natural fit for a small bathroom remodel.

Vanity Countertop Materials for Dallas Bathrooms

  • Quartz. Nonporous and low-maintenance; it does not need sealing.
  • Granite. Durable and heat tolerant, sealed periodically.
  • Marble. Beautiful but soft; acidic cleaners and some toiletries can etch it, so a honed finish hides wear better.

Dallas hard water also matters here. Mineral deposits show most on dark polished stone and on chrome or black faucets. Lighter tops and brushed finishes hide spotting better. For more on stone choices across the house, see our countertops page.

Vanity Replacement, Step by Step

  1. Measure and assess. We measure the wall, the drain and supply locations, the floor tile edge and door clearances.
  2. Design and select. You choose the cabinet, top, sinks, faucets and mirror; custom vanities are drawn for your approval.
  3. Permit if needed. Added or moved plumbing and new circuits are permitted with the city.
  4. Remove and prepare. The old vanity comes out, lines are capped, and blocking or plumbing changes go in.
  5. Install. Cabinet set and fastened, top templated and installed, sinks and faucets connected.
  6. Walkthrough. We run water, check for leaks and test every drawer and door with you.

If a family member uses a wheelchair or walker, an open roll-under vanity with insulated pipes is worth planning; our accessible bathroom remodel page covers that and other clearances.

What Changes the Cost of a Vanity Upgrade?

Custom cabinetry costs more than stock sizes. Stone tops vary by material and size, and cutouts for undermount sinks add fabrication work. Changing from one sink to two, moving the drain, or relocating lights and outlets adds trade work and permits. Floor repair where the old cabinet stood is the most common surprise.

Ready-made cabinets in standard widths cost least; semi-custom and custom builds rise with size, drawer count and finish. A one-piece cultured or integrated top usually costs less than a templated stone top, and wall-mounted faucets add plumbing work inside the wall.

We install vanities in Dallas, Richardson, University Park and Plano, where 1970s to 1990s homes often still have their original cultured-marble vanity tops.

Why Six Design Group for Bathroom Vanities

  • Cabinets designed and built for your wall

    Custom cabinet design, building and installation is part of what we do for kitchens, so a vanity can be sized to the inch and finished to match the rest of the house.

  • Countertops chosen with straight answers

    We install granite, quartz and marble tops. Victoria W. noted we told her when one stone cost twice as much as a nearly identical option, and we compare vanity tops the same way.

  • Detail where it shows

    Ramon H. said in his review, 'Arian was obsessive with the details.' On a vanity that means level tops, even reveals and sinks centered under the faucet.

Where We Do Bathroom Vanities Around Dallas

Bathroom Vanities Questions, Answered

Can a single vanity be swapped for a double?

Yes, if the wall is long enough. Two sinks need a vanity of roughly 60 inches or more, and more width is more comfortable. The plumber adds a second set of supply lines and a second drain connection, often tying into the existing drain inside the wall. On a slab, drains that come up through the floor may need concrete work to reach the new sink.

Are floating vanities strong enough for stone tops?

Yes, when they are anchored to solid framing. A wall-hung vanity with a stone top and a full sink is heavy, so we add wood blocking between the studs before the wall is closed and fasten the cabinet into it. The drain and supply lines also need to sit high enough to hide inside the cabinet.

Can you match the vanity to my kitchen cabinets?

Yes. Because we design and build custom cabinets, a vanity can use the same door style, wood species or paint color as your kitchen. Paint and stain can vary slightly from batch to batch and with age, so for an exact match we compare samples against your existing cabinets in your home's light before the vanity is finished.

What vanity height should I choose?

Many older vanities sit around 30 to 32 inches high, which is low for most adults. Comfort-height vanities of about 34 to 36 inches are now common, closer to kitchen counter height. A vessel sink adds its own height on top. For a kids' bath, a lower vanity or a step stool works; for wheelchair use, an open, roll-under design is the answer.

Can my vanity be replaced without redoing the floor?

Yes, sometimes. Floor tile often stops at the old cabinet base, so a new vanity with a smaller footprint, or a floating vanity, will expose an untiled strip. If the new cabinet covers the same footprint or more, the floor can stay. We check by pulling the old vanity early or matching the footprint exactly.
