After replacing my shower head with an obnoxiously large rain shower head, I found out I would have to lose my shower caddy that hung behind as it no longer fit. This shelving system was a life saver. It actually provides a ton more storage while still saving space! First of all- talk about EASY assembly!! The manual comes with clear directions which tell you just how many pieces you need to fit the space you have. Once you have that info- you’re done in literally minutes! It takes longer to measure the height of your space than to build and install this unit! This is a legitimate tension rod- just like a shower rod- but so much easier to do on your own because it’s vertical. Once installed, it is very sturdy. I have a lot of bath products- like pump shampoos and I am able to pump on them while they are on the shelf and the unit doesn’t budge at all. Also, the shelves fit flush against the corner of my shower- basically taking up no excess space! Each shelf allows for the water to fall through easily, has room to hang wash clothes and even has a separate soap dish. Also important to note- there are four shelves included- you don’t have to use all four, and the ones you do use can be completely customized. You decide how far apart they should be and lock them into place! This has genuinely solved my space issues in my shower and has actually allowed me to buy more products since I now have the extra room! Highly recommend!!
