Installing a Bathroom Vanity

Installing a bathroom vanity is not the easiest of DIY projects to undertake but it is one of the most rewarding. At the end, you will have a completely new area that is not only practical but also livens up the bathroom decor as well.


Removing and Installing a Bathroom Vanity and Sink

The first thing that needs to be done when installing a bathroom vanity is to remove the old sink and cabinetry. As always, turn off any water valves and open the faucet to get as much water out of the pipes as possible before disconnecting the hoses and pipes.

One problem you may come across is that most will be attached to the wall, not only by easy-to-remove screws, but also by caulk as well. That requires a patient, but necessary, slow chipping away with a utility knife until the sink is free of the wall and floor. The alternative is to simply rip it out, but this is likely to result in a much larger refinishing job at the end.

Once the old fittings have been removed, carry out any re-finishing that needs to be done. With such an open and easily accessible area, it is the perfect time to do any needed sanding. Some will be tempted to paint or wallpaper at this stage. That is an option but bear in mind that it really raises the bar on the need to be careful when installing a bathroom vanity in place.

Tips on Installing a Bathroom Vanity Cabinet

Measure the height from the floor and distance from one wall of all pipes and hoses. I assume that you considered those before buying a replacement to fit the space. So this step is to ensure that the replacement slides in to just the right place.

Part of that effort may involve cutting and/or drilling any needed holes in the back of the new vanity. Hot and cold-water hoses have to snake through these in the under-the-sink section. The same applies to the drain pipe(s) from the wall.

Very few floors are perfectly level and even a custom-made vanity will not have had the base cut to compensate. The easiest way to deal with the problem is to shim around the base to prevent any wobble or excess pressure on one side. Then the remainder can be caulked to close up any gaps. It is theoretically possible to shave the base of the vanity instead, but the effort would rarely be worth the trouble.

Once that has been taken care of, the easy steps are all that remains. Locate a couple of wall studs behind the vanity and under the counter top. Use them to provide a secure mounting area to fasten the flat section at the rear of the vanity, otherwise known as a nailer, to the wall. Pre-drill a couple of holes with a bit a little smaller than the wood screws and then fasten.

Lay a bead of plumber’s putty around the rim of the vanity for the sink and lower the sink into place. It will squeeze out some of the putty, top and bottom. Scrape the excess from the top using a cuticle tool or ice cream stick, and then wipe the remainder off with a slightly damp sponge before it dries.

Install the faucet, reconnect the hoses and pipes and turn on the water. There you have it – installing a bathroom vanity is not so difficult after all!
