Many shower and tub walls are either boring to look at or have mold, mildew or cracked or discolored grout joints which are ugly and are a pain to clean. What’s really cool is there is a new composite waterproof wall system (the Sentrel system from the Bath Doctor) which looks great, is easy to maintain and light on the budget. The benefits of this system are outlined below:

Look of marble, granite, stone at 1/2 the cost –If you thought you can’t afford high end bath walls think again.

No maintenance & joints to worry about – These seamless panels have no grout to maintain and do not need to be sealed – a unique scratch resistant PVC composite backed system will look great for years to come.

Waterproof material will not collect bacteria, mold or mildew to keep your family safe – Shower & tub areas can be down right nasty to clean and can be breeding grounds for unhealthy bacteria. Get rid of this problem with the Sentrel system.

Broad selection of colors & patterns that will compliment any bathroom design – Choose from popular travertine patterns (like vanilla, mocha, oro, shara, abalone) or marble and stone looks like Calcutta or Venetian Gold, Breccia Paradiso or Rainforest to name just a few.

Multiple uses – This material can be used for tub and shower wall panels, bench seats, tub decks, tub to shower conversion projects, bathroom walls and even kitchen backsplashes.

Can these tub & shower wall panels be used over existing tile? It depends. If the tile walls are in good condition the Sentrel decorative walls can be applied over. If the old walls are spongy and/or are falling apart then the old tile and wall backer will most likely need to be removed and replaced first.

Can the Sentrel system be applied over one piece fiberglass surrounds? The simple answer is no. In this case our crews will remove the one piece unit, add wall backer board and then apply the new shower or bathtub panels to the backer board.

What is this composite material made of? Will it last over time? Sentrel is engineered to last with a 5 Part Protection System. This 5 Part system includesa clear poly top layer, followed by the high resolution pigment, the Xtra Bond cement, the 1/4" polyvinyl backing with a Dow Corning adhesion layer on the inside.
