My house is 15 years old and built on a slab. The shower stall is an enclosed corner unit made of fiberglass (I think all one unit) enclosed with glass. The slope of the floor of the stall has always allowed water to pool in the corner instead of flowing easily down the drain located in the center of the shower floor. I assume the former owners who built the house did not make sure that it was installed level because this problem has been with me since I purchased the house. With the red clay soil in this part of the South, the shifting of the house could be causing the problem to worsen. What is the best and most cost efficient way to fix this problem so that I don't have pooling water. Should I install a new shower stall or try build up the floor to make it slope toward the drain. What kind of cost is involved in a new stall installation. Thanks so much for your advice.

Hi Mary,

"What is the best and most cost efficient way to fix this problem so that I don't have pooling water. Should I install a new shower stall or try build up the floor to make it slope?"

Your best and cheapest way would be to block the shower floor up level and then build a mound of mortor or cement or wood blocking under the floor to bed it and keep it level. I wouldn't have the foggiest on the cost of replacing it. Good luck Tom

I can only imagine how much work would be involved in taking the doors off, then the base up and trying to re-lvl the thing... (can of worms) I'd say get some estimates to have it replaced, Then go with the plumber you felt the most comfortable with and make sure he is licensed, That's the BEST way to solve the problem.

Does the water pool at the door or along the walls? If it pools along the doors it could be possible to shim under the fiberglass unit edge depending what type of bathroom floor you have and if where the pan sits on the floor is visible. (tile floor or vinyl floor or other type?) Is there gaps in the shower door, does it close well? Is there gaps in the seams of the walls themselves? If so, it may be better tearing out and re-doing it properly.

Thanks for the good suggestions.I appreciate your taking the time to answer.

Mary
