Walk in showers have been popular for quite a while in certain commercial applications, such as at gyms. A walk in shower allows individuals to quickly duck into the shower after working out, and rinse the sweat and dirt off.
Walk in showers have recently become popular in home bathroom designs as well. They offer a unique brand of convenience, flexibility, and style.
Walk in showers are convenient as they allow you to quickly and easily duck in the shower for a quick shower, without having to mess with a stuck shower curtain, etc. They are what you might call a minimal, integrated design.
As far as flexibility is concerned, walk in showers are about as flexible as showers can get. You can create a walk in shower anywhere in your bathroom you can get the correct plumbing to. You can put it in a corner, or even in the middle of the room if you wanted.
Once you do decide that a walk in shower is what you want, you have some great design options. You can create a wet room, which is basically just a corner of your bathroom surrounded by some glass panels to contain the water. This gives you a very flexible design, allowing you to make the shower the right size to fit your specific needs. For example, you could easily make a handicapped accessible shower this way.
There is really no limit to the designs you can create for your walk in shower. You can buy the glass panels separately and create your own unique design. If you can come up with a design, you can probably create it - It's all up to you!
