Installing Fiberglass Bath and Shower Unit

Use Insulation and Asphalt Shingles When Installing a Bathtub

By Mark J. Donovan




When installing a Fiberglass Bath and Shower Unit there are a couple of tips a DIY homeowner can do to help ensure a quieter and better looking finished bathroom.

Use insulation as a noise filter to deaden the sound of falling water. First, lay R11 (3.5″ thick) insulation on the floor where the Bath and Shower unit will be installed. This is particularly important for upstairs bathrooms. Second, hang R11 or R21 (5.5″ thick) insulation between the wall studs where the Bath and Shower unit will rest up against. Future slumbering occupants of neighboring bedrooms will thank you.

For ensuring 90 degree finished sheetrocked walls and corners near the Bath and Shower Unit use strips of asphalt shingles.

Normally the Bath and Shower Unit is secured with Nails or Screws near the edge of the unit. The thickness of the Unit is approximately 1/8 inch thick.

By using narrow strips of Asphalt shingles you can help smooth the transition from the edge of the Unit to the surrounding Stud edge surface, thus creating a more finished wall appearance when the sheetrock is applied.
