FAQ — Extra-flat mineral resin shower tray
What is the composition of the LAVABERG shower tray?
LAVABERG is composed of 75% dolomite (volcanic mineral stone) and 25% high-performance resin, giving it greater strength than 100% acrylic shower trays.
Is LAVABERG suitable for people with reduced mobility?
Yes. It is certified slip-resistant to class C3 (DIN 51097) and PN24 (XP P 05-010), meeting accessibility requirements for wet surfaces.
Can LAVABERG be installed outdoors?
Yes, LAVABERG is UV-resistant and suitable for indoor and outdoor use (garden shower, spa area, etc.).
Why is my shower tray bulging?
Mainly due to rigid bonding or a lack of an expansion joint. You must use an elastic polyurethane sealant.
Can I leave my shower tray on its pallet until installation?
No. It must be stored flat on a rigid surface, never on the transport pallet, to prevent any flexing.
Is it a manufacturing defect if the shower tray deforms?
In 9 out of 10 cases, the cause is related to installation or storage, not the shower tray itself.
Can a LAVABERG shower tray be installed on support points?
Yes, with one support point every 20 cm to ensure uniform support and prevent any flexing.
Which sealant should be used for installation?
An elastic polyurethane sealant, never tile adhesive or thin-set mortar.
Is the warranty still valid if I cut the shower tray?
No. Any modification voids the manufacturer's warranty. The 10-year warranty applies only to a shower tray installed without modifications.
