The ALLZONE Constant Tension Corner owns the customizability crown. It has four tiers of shelves, one of which has shampoo cap holes cut into the bottom for when you are at the end of a bottle. Because of its size, it has a huge amount of storage capacity &mdash; at least enough for four people's products &mdash; maybe more. Each shelf also comes with a bar that can be inserted either pointing upward &#40;to act as a guard against bottles toppling over&#41; or downward &#40;to do its duty as a towel bar&#41;. One of these adaptable bars also comes with hooks for razor or loofa storage, and the shelves and actual towel bar are all adjustable heights.
Our biggest issue with this model is that it takes a little while to assemble. Aside from the several parts, the instructions are not always intuitive. Some folks may also be turned off by the plastic shelves, and while they do have some holes for drainage, body wash and shampoo residue will eventually build up on the bottom. Ultimately, we think that this product is excellent for families that need a lot of storage space for their bath products.

If you can’t use a traditional shower caddy, this tension rod fits into the corner and extends from 5 to 9 feet. Its easy, one-step extension beat out the others we tested.

The Best Shower Caddy

The ODesign Shower Shelf is a super versatile shower caddy. The two-tier design holds shower and bath products for two or more people. The units use adhesive pads with hooks that stick to shower tile very securely. The wires that make up the bottom of the basket are close together, so items don't fall over or fall through. We also think that this shower shelf could easily be a kitchen shelf when installed against a tile backsplash.   
One of the few dings against this shower shelf is that it doesn't come with any hooks. It's not a dealbreaker, but if you were hoping to hang a razor, this model isn't for you. Though we found that it has ample storage capacity, it just isn't as deep as models installed in the corner of the shower. This basic, decent-looking caddy is great for a couple or small family.

The SMARTAKE 2-Pack Corner is a remarkably strong and versatile shower caddy. The 2-tier model that we tested has two baskets, one slightly smaller than the other. They both rely on adhesive pads with hooks to stay put on a wall. We love the deeper baskets, and the pattern of the bottom wiring ensures bath products don't fall through the cracks. Both shelves can bear a significant amount of weight &#40;far more than you would ever reasonably put into either of them&#41;, and they are separate from one another, meaning that you can install them at any height with any amount of space between them.
Our primary issue with this model came during installation. There is a somewhat frustrating degree of precision required to get the orientation of the hooks on the adhesive pad and the wiring of the baskets to line up properly so that they don't interfere with each other when snapping the baskets into place. We got it eventually; it just took more time than it should have. This product also doesn't come with any hooks, so loofas and razors must seek refuge elsewhere. In the end though, this product brings excellent stability and adaptability to shower time.

The KINCMAX Basket Shelf is a versatile, top-performing shower caddy. We love that the four included hooks can be attached almost anywhere on the product, making them great for loofas, razors, and washcloths alike. This model also works well as a spice rack in the kitchen or cleaning supply organizer in a utility or laundry room. The adhesive pad adheres very strongly to tile and stone surfaces, making the whole product incredibly stable. It also isn't beholden to any particular place in a shower &#40;i.e., in a corner&#41;, so it can be installed anywhere along the wall at any height.  
There aren't many downsides to this product. However, we did notice this model only comes with a single adhesive pad for installation. To be clear, that's all you need, but it also means there isn't any margin for error if it doesn't go right the first time. That minor knock aside, there is plenty to like about the simplicity and versatility of the Kincmax Basket Shelf.

More adjustable and versatile than the OXO, this Simplehuman product is a truly excellent shower caddy, although it costs a lot and is not quite as simple to install.
