Why our kit company (kitbedrijf) chooses premium material

Not every sealant is the same. We do not use standard hardware-store products, only OTTOSEAL®. Why?

Color-stable

White stays truly white and does not yellow.

Mould-resistant

Extra protection for wet rooms.

Design choice

Available in many colors, including the popular matte collection for a bold concrete look.

Natural stone

Have marble or hardstone? We use special OTTOSEAL® sealant to prevent edge staining in your expensive tiles.

What we seal in the bathroom

Everything that has to handle water and moisture. Cleanly finished, matched to your tiles.

shower

Shower sealing

The most critical spot. We ensure a 100% watertight seal for floor, walls and drain.

bathtub

Bath sealing

A clean line along the bath creates a luxury look and prevents water behind the surround.

wash

Sink & vanity

The finishing touch. A subtle line between sink and wall keeps it hygienic and clean.

wc

Toilet

No gaps where dirt settles. We finish the connection to wall or floor neatly.

Replace old sealant

Loose, discolored or mouldy? We remove old sealant, deep-clean the joint and reseal.

Color advice

Unsure about color? We bring samples. From bright white to sanitary grey, anthracite or matte black.

Keep your bathroom fresh and watertight

Sealant may seem small, but it decides whether moisture stays out (and whether insurance pays out after a leak). Look for these signs:

  • check_circleMould: black spots that won’t clean out (mould is in the sealant).
  • check_circleSeparation: sealant pulls away from tile or bath.
  • check_circleCracks: small hairline cracks from building movement.
  • check_circleAging: sealant feels sticky or looks yellow.

Tip

Preventing mould starts with ventilation. Our sealant helps with mould-resistant ingredients, but drying after showering still matters.

FAQ — bathroom sealing

Short and reassuring.

What does bathroom sealing cost? expand_more
Start with the Prices & Packages. With a photo we check the situation. We work with fixed prices, so there are no surprises afterward.
I see black dots in my sealant. Do I need to replace it? expand_more
Yes, unfortunately. Once mould gets into the sealant (black dots), you cannot clean it out. Replacement is the only hygienic and good-looking solution.
Can I shower the same day? expand_more
Sealant needs to rest. In most cases it is fully usable after 24 hours. You will receive clear instructions after the job.
Do you have matte colors? expand_more
Yes. We have several matte shades (such as matte grey, matte white and matte black) that look great with concrete-look tiles or natural stone.
Do I get a warranty? expand_more
Absolutely. De Kitbaas provides a 2-year warranty on all sealant work.
