7 Best Corner Shower Shelf Options for New AND Existing Showers

Illustration for 7 Best Corner Shelf Options post featured image

I’ve installed many different shower corner shelves during my bathroom remodeling career. 

So in this post I’ll go over a few of the best ones I’ve installed. 

The first part of my list includes shelves that are generally installed during a full shower remodel. Some of these require tile modification and some don’t. 

The second part includes shelves that can be installed into existing tiled showers. This includes Retrofit shower corner shelves and screw mounted corner shower shelves..

The Problems with Corner Shower Shelves

Shelves that get loose and fall off prematurely is the biggest complaint I hear from my clients about their corner shower shelf purchases.

And if they’re remodelling their shower, other clients have complained that the more sturdy wall mount corner shelves are too big and clunky. 

They also complain about water pooling against the wall, and how soap scum and mold can accumulate.

And still others told me that some stainless steel parts on their shelves have shown signs of rust when cleaning with chlorine bleach products.

Shelves Installed during Tile Installation 

In my opinion, the best type of corner shower shelf is one that’s installed in the shower wall during the tiling stage of a shower remodel.

These shelves are secured to the shower wall with thinset mortar and supported with the tile below. A simple but super secure installation.

This type of corner shower shelf installation seems to holds up to the best, providing many years of problem free service.

Stainless Steel Corner Shower Shelves

My go-to shower corner shelf was always the Shelf-E by Schluter Systems because my clients liked the clean minimalist look of a single sheet of stainless steel.

It was a very nice and functional shelf, but I always thought it could use some improvements to address some of my clients’ shower corner shelf concerns. As a result, I decided to design a stainless steel corner shower shelf of my own (with my brother Dave, actually).

I don’t want to brag too much about our shelf but I will say that it is quite attractive (in my opinion) and it solves all the corner shower shelf problems that my clients have complained about over the years. You can check it out below.

Glass Corner Shower Shelf 

Glass corner shelves are also popular with a modern and minimalist look. These could be mounted in the grout line, or with hangers mounted in the grout line.

This image shows the type of glass corner shelf that is imbedded into the thinset mortar during tiling. 

This shelf usually includes glass tabs on the wall side so the lower tile must be notched at the grout line on both walls so the tabs can be inserted between the tiles. 

If installed correctly, the tiles, mortar, and grout, will securely support the glass corner shelf and anything you choose to place on it. 

It’s strength and stability is one of the biggest advantages of this type of shower shelf.

Glass corner shelves like the one above often have a slight green color, but clear glass is also available if you want to spend a bit more money.

Common complaints that I hear about glass corner shelves is that soap tends to slip off, they don’t drain water away, and they always look messy between cleanings.

Contractors Tip:

Always make sure that the glass shelves you purchase are made from tempered glass or laminated “safety glass”. Untempered glass is very dangerous if it breaks, especially in the shower.

Tile Corner Shelves

Tile corner shower shelves made the list because the are super solid and a popular DIY shower storage idea. 

These are also popular because they’re inexpensive, easy to make, and will match your shower wall tile perfectly if you prefer that your shelves blend in with the surrounding tile. 

Alternatively, some people like to use timber framing to create the shelf ledge, then tile over it. I would not recommend this strategy because any wood framing that extends into the wet area of the shower is a bad idea. 

No matter how well you waterproof this framed shelf before tiling, it will still absorb a small amount of moisture. This means eventual swelling, grout cracking, rot and mold. 

A better option would be to use a piece of foam shower board like Wedi Building Board. Since you only need a single piece of foam board to construct your shelf, it is more solid and less prone to water penetration. 

For adequate rigidity, this type of shelf needs to be at least ¾” thick and imbedded into the  thinset mortar on both sides during a full remodel. In other words, it is not a retrofit style shelf so it cannot be installed into an existing shower. 

Ceramic Corner Shelves

These corner shelves are made mostly of ceramic and occasionally from porcelain and are cured and glazed in a kiln. This gives these shelves a durable waterproof finish. 

Because this is a very old technique, and all the original wall mounted soap dishes were made this way, these shelves tend to have a more traditional (some would say “dated”) look. 

Although the tabs on the edges look like they are designed to be mounted into the grout lines in an existing shower, closer inspection reveals that the tabs are much too big for this.

Installation of this shelf requires three notches to be cut into the lower tiles (on each side) to make room for these bigger tabs. That means it’s not a retrofit shelf and cannot be installed into an existing shower. 

The greatest benefits of these shelves is that they are inexpensive and can hold a fair bit of weight. 

Another benefit of these shelves is that they come in an assortment of different colors so you can more easily match them with your tile color. 

A problem I have heard several times from clients is that they are quite vulnerable to chipping before and after installation. 

Stone Corner Shelves

I believe that these 2cm stone shelves can be one of the best looking permanent corner shower shelves, if they match well with the surrounding wall tile. 

I really like this shower shelf idea because it can be inexpensive, a lot more structurally solid than tile, and looks more professional and attractive. 

When a stone corner shelf is imbedded into thinset mortar during shower wall tile installation, this shelf can carry an immense amount of weight, making it great for a corner foot rest or shelf. 

Stone pieces like this are generally available in a 2 cm thickness, but 3cm can also be found with certain stone varieties for a bolder look. 

The 2cm shelves are pretty easy to find online, but I must warn you not to be enticed by the cheaper stone corner shelves (in the $20 – $30 range).  I have found that many of these tend to be broken when you get them, or they fracture during handling and installation. 

Contractor’s Tip: 

If you call your local stone fabricator they often have dozens (sometimes hundreds) of stone remnants too small to sell to their regular buyers. 

And because they have no use for all this extra “junk” they regularly send it all to the dump (or recycling depot hopefully). If you speak to them nicely they will often cut and polish a small piece for you for dirt cheap. 

And if they won’t cut and polish it, you can probably still buy a small piece from them and try cutting and polishing it yourself. It’s actually not that difficult! There a few good DIY posts online about cutting stone and polishing stone, if you’re interested.

Corner Shelves for Existing Tiled Showers

If you want to install a shower shelf in the corner of a shower that’s already been tiled, you’re mainly looking for a Retrofit Corner Shower Shelf or a Screw Mounted Shower Shelf.

Most of the corner shower shelves discussed in the section above can only be installed during a full shower remodel because they are imbedded in the thinset mortar during tiling, and supported by the tile below the shelf. 

But this section includes the shelves that are designed to be installed into an existing tiled shower wall.

Retrofit Corner Shower Shelves 

How do you install shelves into an existing tiled shower

The easiest way to install a corner shelf into an existing tiled shower wall is to use a retrofit corner shower shelf because they are attractive, sturdy, do not damage the waterproofing membrane, and install easily by removing a bit of grout. 

Stainless steel corner shower shelves are among the most popular corner shelves because they have a very thin profile, can match most metallic fixture finishes, AND can be installed into the corner of almost any existing tiled shower wall. 

As I mentioned previously, my favorite stainless steel corner shelf is the shelf that my brother and I designed. The rb3 Corner Shower Shelf. 

The reason it belongs in this Retrofit Corner Shelf section as well as the above section, is because it can easily be installed during a full remodel OR an existing shower, as long as the grout lines are 1/8 inch or larger.

The best thing about retrofit shelves is that they can be installed fairly easily and they don’t penetrate the shower wall waterproofing membrane if installed carefully.

The main disadvantage of the retrofit shelf is that if you need to remove grout to make room for the mounting tabs. This requires a bit of skill if your planning to use a power tool (like a multi-saw), but it can also be done very safely if you drill some pilot holes and use a hand tool designed to remove grout.

Screw Mounted Corner Shower Shelves

Screw mounted shower shelves are slightly less secure than those installed during tile installation, but they’re much more solid than the temporary shelves like Suction and Adhesive Shower Shelves. 

That makes these shelves popular for people needing stronger, more reliable shower storage but are not interested in a full shower remodel. 

The main problem with screw mounted shower shelves is that the screw anchors mount into the tile backer board. That means you must drill through the tile and waterproofing membrane in order to attach them. 

Breaching the waterproofing membrane is generally not a good idea even if the drill holes are very small. 

However, if you choose an install location opposite the valve wall (outside the splash zone), and surround the screw holes with silicon, I’m generally OK with this kind of installation. 

Another problem is that most of these shelves utilize plastic screw anchors to secure the shelf in place, and these anchors are not reliable when used with tile. They are usually not long enough, and the tile hole is too slippery to keep the anchor in place which causes them to wiggle out over time. 

The best way to install these shelves is to find a location that allows you to screw at least one of the mounting screws into a wall stud so the screw can hold firmly. However, this can be a challenge considering there is not often a stud located a few inches out from the corner where the screw is to be attached. 

Corner Suction Shower Shelves 

Corner suction shower shelves are one of the most popular type of temporary shower storage shelves because they are generally inexpensive and super easy to install. 

However, I don’t recommend these shelves simply because they do not last, and they’re not nearly as sturdy as the other options I’ve mentioned above. 

As compelling as it is to buy this “easy shower storage solution”, most people end up abandoning their suction shelf when it crashes to the shower floor in the middle of the night.

Adhesive Corner Shower Shelves 

Not surprisingly, adhesive shower shelves are also super popular because they are inexpensive, easy to install, and they can look a lot like permanent built-in shower shelves. 

The problem is that they don’t even have structural stability of a some suction shower shelves, let alone a permanent shelf because adhesive pads are unreliable in a wet environment and will eventually fail.

As such, I don’t generally recommend the installation of any of these shelves. 

Wrap Up 

I hope you’ve got some insight from my shower corner shelf post. 

I’m sorry if it was not as comprehensive as you’d like, but there are so many different varieties of corner shelves that I felt I needed to narrow it down to those I’ve had experience with and those that I preferred. 

If you think ‘ve missed some important info or I should have covered one of the categories better, please let me know in the comments below and I’ll do my best to include it in my next update! 

Good luck with your corner shelf search and your shower upgrade!

    Hi Sharon,

    The basic rule for corner shelves is to install them where they’ll be most convenient for you personally. In other words, there’s no standard “rule” for this.
    I’ve heard some of my customers say that they don’t like them on the shower head side because they don’t like standing in the water stream when accessing their shower products.
    Others are not irritated by this at all, and prefer this location because their products are always within easy reach.
    Some people have also told me that their bar soap melts away faster on the shower head side, but I don’t think this would be a concern unless they’re installed too low (more water splashing).

    Good Luck!

    Please recommend where the corner shelves should be placed & why: either close to the shower head or the corner furthest away?
