Basement Bath Bryn Mawr PA. Want a basement bath from scratch? Sure, no problem its nothing a little jackhammering concrete and digging trenches for plumbing can’t solve. We changed a doorway to an unfinished storage area to a spacious full bath and hall with access to the remaining storage area. Now family and guests have a more convenient bath when hanging out in the finished basement. The clients also wanted a full shower for the kids after sports, guests staying over, or after a workout in the adjoining fitness room. Some interesting ceiling work was needed to go around the homes existing mechanicals while still maintaining a comfortable ceiling height. Durable and stylish vinyl floating floors are a great choice for the flooring. The Dreamline shower system looks clean and bright. The new bath and hall blend seamlessly with the already finished basement and seem original to the space.
