Shower enclosure
This comes in various shapes: quadrant, rectangle or single door if between two walls. The frameless ones are better at cleaning compared to the old style enclosures.
Bifold doors are especially useful for awkard spaces like ensuites.
Walk in showers
This is an increasingly popular option since the walk-in shower size is more or less similar to a bathtub. It’s also easier to maintain.
You can get a walk in shower with a fixed glass or with a fixed glass + flipper panel. You can also get a glass at the end of the walk in shower (unless you have a wall there).
A walk in shower is useful when having sloped ceilings as well, since you can utilise the space better there.
Wetroom
This is probably the most expensive type, but probably the best looking option. You no longer have a tray. This means that the floor has to be waterproofed/tanked. A wetroom improves the look and utility of a room dramatically, but it’s the most expensive option.
If getting as much of the space as possible is the goal, a wetroom is usually the best option, despite the extra expenses.
With a wetroom, we’ve used in the past seats made out of tiles. These are great for people that need a seat inside their showers, but they still want the room to have that luxury feeling.
