Vanity Tops & Bathroom Countertops in Los Angeles, CA

Quartz, granite or marble vanity top: how they compare

Bathrooms are kinder to stone than kitchens, since there is no hot cookware or chopping. The bigger risks are toothpaste, cosmetics, hair dye and cleaners.

More on each material is on the quartz countertops, granite countertops and marble countertops pages, which cover kitchen use but apply to baths too.

Prefab vanity top or a piece cut from slab?

A prefab vanity top is made in standard widths, with the sink cutout, faucet holes and often a matching backsplash ready to go. It is the cost-efficient choice for a standard 24-, 30-, 36- or 48-inch vanity in a hall bath, guest bath or rental. The prefab countertops page explains how they are made.

A top cut from a full slab makes sense when the vanity is a non-standard width, wraps a corner, sits between two walls that are out of square, or needs to match a kitchen counter elsewhere in the house. It also lets you choose the exact section of a granite or marble slab, which matters when the stone has strong movement.

Questions that decide it

• Is the vanity a standard width, and is it freestanding or tight between walls?
• Do you want a particular edge profile, or is an eased edge fine?
• Is one sink or two, and what faucet spread: single hole, 4-inch centerset or 8-inch widespread?
• Does the top need to match other stone in the house?

Bathroom countertop replacement on an existing vanity

Replacing only the top is common when the cabinet is solid and the finish still works. Before shopping, check that the cabinet is level and dry, that the doors and drawers close, and that the sink base has no soft or swollen panels. A top is heavy, and a weak box will not carry stone well.

1. Measure the cabinet width and depth, not the old top, and note whether the old top overhangs the sides.
2. Note the faucet type and how many holes it needs, plus the sink style you want.
3. Look at the wall behind: removing a top with an attached splash can expose unpainted or damaged drywall.
4. Plan for the plumbing: the faucet and drain are disconnected and reconnected, while moving supply lines or the drain is a job for a plumber.

Signs the old top has had its day

• Hairline cracks or crazing around the drain of a cultured marble top.
• Etched or ringed marble where soap and toiletries have sat.
• Swollen cabinet panels under the sink from water getting past failed caulk.
• A dated single bowl where you now want two sinks or a wider counter.

If the vanity is also due for replacement, the bathroom vanities and cabinets page helps size a new one, and the top can be ordered to match.

Sinks, backsplashes and edges for vanity tops

The top, sink and faucet are ordered together, because the cutout and holes are made for a specific sink and faucet.

• Undermount sinks sit below the stone so you can wipe water straight into the bowl. They are the most common choice for daily-use baths.
• Vessel and glass bowl sinks sit on top and act as a centerpiece. They suit powder rooms and need a taller faucet or a wall-mount spout.
• Backsplash: a 4-inch splash in the same stone is standard on many tops; a full tile backsplash or a stone splash to the mirror are alternatives.
• Side splashes are useful when the vanity sits between two walls.
• Edges: eased and beveled edges are simple and clean; bullnose and ogee profiles suit traditional rooms.

Choosing a top at the showroom

1. 1

   Bring cabinet dimensions and a photo

   Width, depth, height, and whether the vanity sits between walls or stands free.

2. 2

   Pick the material

   Compare quartz, granite and marble samples against your vanity finish and tile.

3. 3

   Choose prefab or slab

   Standard widths often fit a prefab top; anything unusual is cut from slab.

4. 4

   Select sink, faucet spread and edge

   These set the cutouts, so they are decided before ordering.

5. 5

   Confirm measurements and install

   Measurements are checked against the actual cabinet, then the top is installed on request or picked up for your own installer.

What moves the price of a vanity top?

• Prefab versus custom-cut. Standard prefab sizes cost less than a top fabricated to a template.
• Material and color. Within each material, rarer colors and patterns cost more.
• Size and sink count. A 72-inch double top uses far more stone and needs two cutouts.
• Edge profile. Ogee and bullnose edges take more fabrication time than an eased edge.
• Splashes. Matching side splashes or a full-height stone backsplash add material.
• Removal and reconnection. Taking out an old cultured marble or tile top and reconnecting the faucet and drain add labor.

Caring for bathroom countertops in Los Angeles homes

Wipe the top dry after use, especially around the faucet base, where hard Southern California water leaves mineral rings. Keep perfume, nail polish remover and hair products on a tray, since some of them can mark quartz and many will etch marble. Use a pH-neutral cleaner rather than vinegar or bathroom sprays with acid. Granite and marble benefit from a penetrating sealer on the maker’s schedule; a simple water-drop test shows when it is time. Re-caulk the joint between the top and the wall if it cracks, so water does not reach the cabinet.

Rules that touch a top-only swap

Setting a new top on the same vanity, sink and faucet in their old spots, is generally not permit work. Moving a drain or adding a second sink is plumbing: that calls for an LADBS permit inside Los Angeles city limits (other cities issue their own) and a C-36 plumber whose license you can confirm on cslb.ca.gov. Under the California Energy Commission’s Title 20 rules, new bathroom faucets sold in the state are limited to 1.2 gallons per minute.
