Six ways a bathroom fixture attaches
Drilled mounts
A fastener passing through the wall into whatever is behind it, for good.
A drilled mount is the only one on this site where the load path ends in the building itself rather than in a pad, a pipe, a spring or the floor. That is why it is the strongest option and why it is the last one you should reach for in a bathroom.
This page will not tell you which bit to use, what anchor to buy, or how to get through a tile without cracking it. That is deliberate. Behind the wall of a bathroom there are supply lines, a drain stack and electrical runs feeding lights, fans and outlets, and the two ways this goes wrong are a flooded ceiling below and a shock. Neither is a project you recover from with filler.
The rule this site works to: if you do not already know what is behind that wall, this is a job for someone who can find out. That is not caution for its own sake. It is the difference between a shelf and a claim on your insurance.
Section one
What holds it
The structure of the building, through a fastener sized to the wall it is going into.
- The heaviest loads on this site by a wide margin, when the fastener is right for the wall and the wall is right for the load.
- Loads that pull outward as well as downward, which is the case adhesive is worst at.
- Anything that has to stay exactly where it is put, permanently, without shifting when it is used.
- Wall-anchor hardware supplied with tall freestanding furniture, which is the one drilled application this site actively points you toward rather than away from.
Section two
How it comes apart
5 ways this mount stops doing its job, in the order they turn up in practice.
- The wrong fastener for the wall. Drywall, plaster, tile over cement board and tile over drywall all behave differently, and a fastener that works in one pulls straight out of another.
- Hitting something. Pipes and cable are behind bathroom walls, and neither is visible from the room side.
- Cracking or spalling the tile at the entry point, which cannot be undone and which opens the tile face to water.
- Water finding the hole. A penetration in a wet wall is a path for water into the wall cavity unless it is sealed correctly.
- Overloading a fastener that went into board rather than into framing, which holds fine empty and lets go loaded.
Section three
What it leaves behind
Holes, and in tile they are essentially permanent.
- A hole in painted drywall is filler, sanding and paint. Most people can do that and most landlords have seen it.
- A hole in a glazed tile is a hole in a glazed tile. It can be plugged and it can be colored, and it will still be visible, and matching a discontinued tile is not realistic.
- A penetration through a shower surround or a tub wall is a waterproofing question as well as a cosmetic one.
- Assume every hole you put in tile is there for the life of the tile.
On the reversibility axisPermanent, and in tile visibly so.
Before you put one up
- This site gives no drilling instructions of any kind. Drilling into tile and into the wall of a bathroom is work with real consequences, and if you do not know what is behind that wall, bring in someone who does.
- Supply pipes, drain lines and electrical runs share the wall cavity in a bathroom. A flooded ceiling and an electric shock are the two failure modes and neither is recoverable at home.
- Where a tall freestanding unit ships with wall-attachment hardware, use it, and get help fitting it if the wall is tiled.
If you rent
The hardest mount to justify in a rental. Holes in tile are effectively irreversible, and a lease may address holes, fixtures or alterations directly. Read your own agreement and ask your landlord in writing before anything goes into a tiled wall. This site does not give legal advice and cannot tell you what your lease permits.
This mount on each surface
| Surface | Verdict | What decides it |
|---|---|---|
| Painted drywall | Accepts fasteners well and patches convincingly | The board hides pipes and cable. Knowing what is behind it is the whole job. |
| Ceramic tile and grout | Strongest hold, permanent consequence | A hole in a glazed tile is there for the life of the tile. |
| Glass shower door | Impossible. Tempered glass shatters entirely | There is no technique and no bit. The panel is destroyed the moment it is penetrated. |
| Fiberglass and acrylic surround | A waterproofing decision, not a storage one | A hole in the shell lets water behind it, where nobody will see it for years. |
| Textured paint and wallpaper | Mechanically normal, cosmetically unforgiving | The fastener goes to the board behind. Matching texture or paper afterward is the hard part. |

Only drilled mount in this category
Every other listing here rests on the floor. This is the one that fastens to the wall.
QEEIG Floating Shelves Over Toilet, Set of 3, 16 in
The listing states wall-mounted floating shelves.
Three 16 inch floating shelves that fasten to the wall above the tank instead of standing on the floor. The mount is the whole difference: nothing here can go over, because nothing here is standing up. What it can do is come out of the wall, and it leaves holes when it does.
- Stated size
- 16 in wide per shelf (per listing)

In its favor
- Nothing stands on the floor, so the area around the toilet stays open and mops properly.
- Wall-mounted shelves cannot be pulled over by a child hanging off them the way a tall frame can.
- A stated 16 in width each, so the fit above a standard tank can be worked out on paper first.
- Three separate shelves means you set the spacing rather than accepting a fixed frame.
Against it
- This one goes into the wall, and holes above a toilet are not something a renter puts back.
- No load figure is stated, and a floating shelf carries everything on a short cantilever.
- Whether it can be fastened at all depends on what your wall is made of and what is behind it.
Best for
An owner who wants the floor clear, is certain about what is behind that wall, and is willing to bring in someone who can be certain if they are not.
