Walk in showers are becoming the new trend in contemporary bathrooms. They are sleek and stylish, allowing plenty of room for more than one person to bathe. The first thing you will need to do is designate a space in the bathroom for the enclosure to go. Generally, corner areas are popular because they are spacious and do not take up too much floor space. Once you have determined where you want the bathing area to go, consult with a plumber to ensure that proper drainage will be possible. To help with draining, plastic trays can be installed on the bottom of the tub that will help catch the water without it overflowing.
