Book a bathroom renovation quoteWe do not carry out isolated repairs or partial renovations. We take on exclusively comprehensive projects in which we have full control over the process - from waterproofing to the final silicone bead. That is the only way to deliver a result we can stand behind.
In every ARVION bathroom the same technical standard applies: two layers of waterproofing with a minimum 24-hour water test, flexible C2S1 adhesive, a levelling system for tiles, aluminium corner profiles, and correct drainage falls. This is not an optional standard - it is our minimum.
