There many options for installing your shower and bathtub accessories. This is especially the case for shower caddies and baskets. Your decision on the mount will be influenced by the item you are considering, what style you want, and how your bathroom is used.
Freestanding caddies and baskets can be placed around the room, stand in the shower, or on a corner of the bath.
Their portability makes them great for when multiple people share a bathroom. Each person gets their own small caddy, and they can switch them about as needed.
Another idea is to place larger caddies in the corners of the room for people to store their bottles outside the shower, so they can just grab what they need on the way.
A potential downside of this style is that it could add to surface clutter, or accidentally get knocked over.
For space-saving hanging caddies are ideal. These are designed to be suspended from the showerhead, shower curtain pole, or the side of the bath to allow you to make good use of the available space.
Suction mounts work similarly - they can quickly be attached to tile or glass. However, be a little cautious about moving these around too often as if they are not correctly placed, they could fall.
With each of these options, you also need to be careful with weight. This is especially the case with suction mounts and hanging caddies placed on flimsy structures.
If you are entirely clear about how much storage you need and where you need it, the drilled mount gives the most stable solution. This is also best for shower shelves and baskets.
With a drilled mount, you can be sure that the fixture is sturdy and able to hold multiple bottles, large ornaments, or anything else.
The downside is that you will be making permanent alterations to your bathroom. So it won't be easy to change your mind if you want something else at a later date.
