Bathroom Accessory Heights: Toilet Paper Holder, Towel Bar, Grab Bar and More

You've got the drill out and a toilet paper holder in your hand. How high does it go? How far from the toilet? And while you're at it, where do the towel bar and the robe hook go?

There's no single building code for most bathroom accessories in a private home. There are, though, two solid references. The National Kitchen & Bath Association (NKBA) publishes Bathroom Planning Guidelines that designers use for homes. The 2010 ADA Standards for Accessible Design set the rules for public and accessible bathrooms. For towel bars and hooks, where neither gives a single number, we use the heights that home guides like Bob Vila and House Digest report as standard practice. Every number below says where it comes from.

Bathroom Accessory Heights at a Glance

All heights are measured from the finished floor, so measure after the tile or flooring is down.

Toilet Paper Holder Height

The NKBA recommends centering a toilet paper holder 26 inches above the floor and 8 to 12 inches in front of the edge of the toilet bowl. That puts the roll within easy reach while you're seated, without twisting or leaning back.

The front-of-bowl rule matters as much as the height. A holder mounted behind you, level with the tank, is the most common mistake: you have to twist around to reach it. Measure from the front edge of the bowl, not from the wall behind the toilet.

Where you mount it depends on what's beside the toilet:

• A side wall. Mount it on the wall at 26 inches, 8 to 12 inches ahead of the bowl. This is the NKBA layout.
• A vanity beside the toilet. Many people mount the holder on the vanity's side panel. A Lily Ann vanity sink base like the Craftsman White Shaker 30-inch is 34-1/2 inches tall before the countertop, so a holder at 26 inches lands on the side panel with room to spare. Use short screws so they don't poke through into the cabinet.
• Open space. A freestanding holder works when there's no wall or cabinet within reach.

ADA Toilet Paper Holder Rules

In an ADA bathroom, section 604.7 of the ADA Standards says the dispenser must be 7 to 9 inches in front of the toilet, measured to the center of the dispenser. The outlet, where the paper comes out, must be 15 to 48 inches above the floor and "shall not be located behind grab bars." The dispenser must also allow continuous paper flow.

If the holder goes above the side grab bar, the ADA's advisory note says the outlet must still be no higher than 48 inches. Section 609.3 also requires 12 inches of clear space above a grab bar, so plan the holder and the bar together.

Towel Bar Height

The standard towel bar height is 48 inches from the floor to the center of the mounts. Bob Vila calls this the industry standard. It keeps a folded bath towel off the floor and within easy reach for most adults.

A few rules from Bob Vila's towel bar height guide help when 48 inches doesn't fit your room:

• Stacking two bars. Fold your largest towel in half, add 2 inches, and hang the lower bar at that height. Then hang the upper bar that same 2 inches plus the folded towel length higher, so the top towel clears the bar below.
• Outlets and switches. Leave about 4 inches between a towel bar and any outlet or light switch, so a wet towel isn't hanging over them.
• Over a vanity. Bob Vila's 48 inches assumes a vanity 30 to 32 inches tall, which leaves 16 to 18 inches for a hand towel to hang. Lily Ann vanity cabinets are 34-1/2 inches tall before the countertop, so a bar at 48 inches would sit less than 14 inches above the cabinet, and less once the top is on. Over a taller vanity, raise the bar until a folded hand towel clears the counter.
• Kids' bathrooms. Bob Vila suggests no higher than 36 inches for ages 3–4, 40 inches for ages 5–8 and 44 inches for ages 9–12.

Towel bars for accessible bathrooms

The ADA doesn't set a towel bar height, but it does set reach ranges. With nothing in the way, the highest point a seated person can reach forward is 48 inches (ADA 308.2.1). Reaching over a counter is harder: if the reach is more than 20 inches deep and up to 25 inches, the maximum drops to 44 inches (ADA 308.2.2).

That matters for a towel bar on the wall behind or over a vanity. Lily Ann vanity sink bases are 21 inches deep before the countertop, so a bar you reach across the vanity for belongs at 44 inches or lower if someone in the house uses a wheelchair. Our ADA bathroom vanity guide covers the vanity side of an accessible bathroom.

Towel ring and hand towel height

A towel ring hangs below its mount, so measure to the bottom of the ring. Bob Vila's rule is to put the bottom of the ring at 48 inches, then add the distance from the bottom of the ring to the center of its mount. For example, a ring that hangs 6 inches below its mount goes up at 54 inches.

Put a hand towel ring or short bar within arm's reach of the sink, on the wall beside the vanity or on the vanity's side panel. A ring beside the mirror keeps the hand towel next to the sink without taking counter space.

Towel storage inside the vanity

If wall space is tight, some towels can live inside the vanity instead. Two Lily Ann cabinet organizers showed In Stock on September 30, 2026:

• The Pull-Out Towel Bar (LAC563-51-C) fits sink and vanity cabinets. It's listed at 12-7/8 inches deep, 3-7/8 inches wide and 1-1/2 inches high, and slides out to dry a hand towel.
• The chrome Towel Holder (LAC563-32 C) mounts on the inside of a cabinet door and fits best on doors 14-1/2 inches wide or wider. It's listed at 12-3/4 inches wide, 6-1/2 inches high and 3-1/2 inches deep.

These hold hand towels and cloths. A bath towel still needs a bar or hook on the wall.

Robe and Towel Hook Height

House Digest puts the general placement for a robe hook at 70 inches above the floor, and says to adjust it for your family's heights. That's high enough that a long robe doesn't drag on the floor. Hooks on the back of a door follow the same rule, as long as the door can still swing open all the way.

In an ADA bathroom, coat hooks must be within the reach ranges in section 308, which means 48 inches or lower (ADA 603.4). For kids, a low second hook is easier than asking them to reach a 70-inch one.

Hooks also dry towels faster than a bar, because the towel hangs loose instead of folded over itself. Our bathroom hardware ideas cover finishes and styles for hooks, bars and holders.

Grab Bar Height and Placement

Grab bars go 33 to 36 inches above the floor, measured to the top of the bar. That's the rule in the ADA Standards (section 609.4) and the height the NKBA recommends for homes. Bars in public bathrooms must be horizontal, 1-1/4 to 2 inches thick, 1-1/2 inches from the wall, and strong enough to hold 250 pounds.

Here's where they go, from the ADA Standards:

Keep 12 inches of clear wall above a grab bar and 1-1/2 inches below and at its ends (ADA 609.3). Shower controls and fittings may sit as close as 1-1/2 inches above it.

Do homes have to follow these rules?

No federal rule requires grab bars in a private home. The ADA Standards cover public and commercial buildings, and even there, section 604.5 lets residential dwelling units skip the bars as long as the walls are reinforced so bars can be added later.

That reinforcement is the step to copy at home. The NKBA recommends preparing tub and shower walls during construction so grab bars can be installed to support 250 pounds. If the walls are open for a remodel, adding solid blocking between the studs now costs little. Drilling for it later means opening tile.

Towel bars are not grab bars. A towel bar held up by drywall anchors can pull out of the wall if someone grabs it to catch a fall.

Mirror, Medicine Cabinet and Shelf Heights

A mirror or medicine cabinet over the vanity is set by eye level, not by a fixed number. Our medicine cabinet size guide walks through it: Bob Vila puts the center of the mirror at about 64 inches from the floor, and Family Handyman puts the top at about 70 inches. Our vanity mirror size guide covers widths.

For accessible bathrooms, the ADA sets two limits (603.3). Over a sink or counter, the bottom of the mirror glass can be no higher than 40 inches. The ADA's advisory note adds that the top of a mirror should be at least 74 inches up, so it works for both standing and seated users. ADA shelves go 40 to 48 inches above the floor (603.4).

The vanity sets the starting line for all of this. A standard vanity and a comfort-height one put the counter, sink and mirror at different heights. Our bathroom vanity height guide explains the difference.

Before You Drill

1. Measure from the finished floor. If new tile or flooring is going in, wait until it's down, or add its thickness to every mark.
2. Find the studs. Heavy or often-used items like towel bars and every grab bar should be screwed into studs or solid blocking.
3. Check for pipes and wires. The wall behind a toilet or vanity often carries plumbing. Use a detector before you drill.
4. Tape it first. Mark each spot with painter's tape and have everyone in the house try it. Moving tape is easier than patching holes.
5. Plan around the vanity. Make sure a bar or holder on the wall doesn't block a vanity door or drawer from opening.

The Takeaway

For most homes, put the toilet paper holder 26 inches up and 8 to 12 inches in front of the bowl, towel bars at 48 inches, robe hooks near 70 inches, and grab bars at 33 to 36 inches to the top of the bar. For an accessible bathroom, follow the ADA numbers above, keep towels and hooks within 48 inches, and reinforce the walls for grab bars before the tile goes up.
