Bathboard

„Quick cladding for wall-mounted baths.“

Product information

wedi Bathboard cladding is made of 20 mm wedi building board and has revolutionised the cladding of bathtubs and showering trays. Height variations because rough concrete and screeding of up to 10 cm can be compensated for during installation by using height-adjustable feet. Installing a control framework is not necessary.
