A bathroom vanity you can use sitting down

Pull a chair up to most bathroom sinks and your knees meet the cabinet doors before your hands reach the faucet. Nobody notices until someone in the house starts using the sink from a wheelchair, a walker seat or a stool, sometimes for a few months after a hip or knee surgery and sometimes for good. This is for the homeowner planning to stay put, or the son or daughter planning the house around a parent who wants to.

Can a vanity leave room for your knees and still hold anything?

Yes. A custom bathroom vanity built for seated use leaves the middle open under the sink and moves the storage to the sides, as a drawer stack or a tall tower on one side or both. Where the counter height leaves room above the knees, a shallow drawer can run across the top of the opening. Most of what a sink base held fits in the side drawers.

A stock vanity is built the other way around. It is a closed box to the floor with doors in front of the trap, which is exactly where a seated person’s knees and a wheelchair’s footrests need to go. The usual workaround is a bare sink on brackets, which gives the knees their room and takes away every drawer in the bathroom. Then the hairbrush lives on the toilet tank and the spare towels live in a basket on the floor.

The side stacks can run to the floor or stand on legs, depending on whether the footrests need to swing under them as well. That shallow drawer over the knees is usually the first thing dropped. It needs its own height plus the thickness of the top, and in a vanity set low for someone sitting, that space belongs to the knees.

How high should a vanity sit for someone who uses it seated?

At the height the person in the chair needs, measured with them sitting in the chair they actually use. The usual published reference is the 2010 ADA Standards for Accessible Design, which for public buildings puts a lavatory counter at no more than 34 inches with at least 27 inches of knee clearance under it. Those are public-building figures, not a rule for a house.

In a home they are a starting point. Wheelchairs differ in seat height, and a person on a bath stool sits differently from one in a transport chair. Armrests decide how close anyone can pull in. So the measure happens with the user in the room, sitting the way they sit every morning, and it checks the reach to the faucet handle as well as the knees. The thickness of the top and the depth of the sink bowl both come out of the knee space, so a shallow bowl gets chosen early in the drawing.

Sharing the room with someone who stands is where it gets harder. A counter that is too high does not work from a chair at all. A standing user can bend a little at one that is low, so a single vanity usually gets set for the person sitting. If the wall is long enough there is a better answer: two heights in one run, an open-knee section at the sink the seated user takes and a standard-height cabinet with full storage beside it, built and finished as one piece.

What covers the pipes when there is no cabinet under the sink?

A removable cover panel, finished to match the vanity, closes off the trap and the supply lines at the back of the knee opening. Without one, the drain and the hot water line sit right where knees and shins go, and the hot line can burn a bare shin. An insulated wrap from a plumbing supplier covers the pipes too, but a panel looks like part of the cabinet.

The panel is cabinetry. It runs straight across or at a slant behind the knees, and it comes off with a couple of screws or lifts off its clips, so the trap can be reached later without pulling the vanity apart.

What sits behind it is the plumber’s work. The drain can often be pushed back toward the wall with a trap that tucks in closer, which buys the knees some depth. Whether that is possible depends on what is inside the wall, and the plumber answers it before the vanity is drawn.

Drawers or doors when you are sitting down?

Drawers, nearly every time. A door swings out toward the chair, so a seated person has to back away to open it and then lean forward into a dark box. A full-extension drawer comes out to the person and shows everything in it from above. The side towers of a seated vanity end up mostly drawers.

• Full-extension slides, so the back of the drawer reaches the user instead of stopping halfway out.
• Pulls a hand can hook into, a bar or a cup, instead of small knobs that need a pinch.
• Soft-close on every drawer, so one pushed shut does not bounce back into a knee.
• Heavier things in the upper drawers of the tower, lifted out sideways instead of up from the floor.

A door still earns its place high on a tall tower, for the spare towels and the things a standing partner reaches for.

Where do the mirror, the outlet and the grab bar go?

A mirror that starts low or runs all the way down to the backsplash lets a seated person see more than the top of their head, and a medicine cabinet hung for a standing reach is out of reach from a chair. The outlet moves to the face of a side tower, so nobody reaches across a wet sink to plug in a hair dryer. A grab bar goes into the wall, never onto the vanity.

People lean on a vanity top and push up from it anyway, and a top screwed down to a cabinet was never meant to take a person’s weight coming up out of a chair. While the old vanity is out and the wall behind it is open, that is the moment to put blocking in the studs where a real grab bar will mount, even if the bar itself comes later. The bar’s exact spot and its installer belong with the rest of the bathroom work. The cabinetmaker leaves that wall ready and keeps the vanity out of the bar’s way.

What if the only full bathroom is upstairs?

Then the bathroom downstairs becomes the one used every day. Many of Marion’s older houses keep their only full bath on the second floor, so when the stairs stop being an option, daily washing moves to the half bath off the kitchen or to a back room converted for it. Those rooms were never sized for a chair, and the vanity has to be narrow and shallow and still leave the knees their space.

In a room like that the vanity often gets one tower instead of two, set against the wall away from the door, with the knee opening on the side the chair comes in from. The shower and a wider doorway belong to a remodeler and get planned alongside it.

On price, most custom vanities in the Marion area run $2,500-$7,000. The pricing page breaks down what a custom vanity costs and what moves the number. An open-knee vanity does not come in cheaper for having less cabinet under the sink. It trades the sink base for side towers, a cover panel and finished sides around the opening, and each of those takes shop time of its own.
