method of masking the seam should be selected based on the materials used for the walls. If this tile, then you can put a side border of its residues left over after repairs.If this plastic panels, just lay on top of the seam edge of plastic.If the walls are painted, the paint yourselves with the same paint and weld, pre-stopper it.

Polyurethane foam

Faster, but less versatile than the grout tool - a foam. With its help seal the gap between the wall and the bathroom can be a matter of minutes.In contrast to the solution, the foam core can be placed on a dry surface.Therefore, after you clean and degrease the gap, blot it from the inside with a dry cloth and leave to dry for a while.

  2. After lying on the drying time of a sharp knife, trim the edges so as to obtain a more even surface as possible.

most modern means - a silicone sealant. The stores represented a large selection of sealants intended for different uses.Among them you need to find a sealant for the bathroom, as in its composition have antibacterial substances that prevent the formation of mold.Sealants come in different colors, but we advise you to buy a transparent, as the most versatile option.

Plastic plinth

Mouldings plastic - the most popular of all the skirting boards to the bathroom.They are successfully used for sealing the gap between the wall and the bathroom.Skirting PVC can be easily and quickly set up and just as easy to dismantle.In addition, plastic - rather soft and elastic material, so a plinth can be adjusted to the size of the bath without any problems.

In stores you can find plastic moldings with a ready-made adhesive backing.We recommend not to use them in a bathroom, because the adhesive composition applied to them, are not usually waterproof.Better use of water-resistant adhesive for plastic.It should be white, and even better - colorless.Be sure to choose a quick-composition, since you have to press the baseboard until until the glue sets.

curb tape

Another inexpensive modern method that does not require much effort - is to use ribbon curb.It is made of polypropylene and is impregnated with a special compound that prevents the formation of mold.


  • requires no decoration;
  • characterized by high resistance to water, so it can safely be used in conditions of high humidity.

The only drawback of this method is that even the best quality curb tape will serve you no more than two years.But with the active use of the bathroom you have to change it every year.

width and thickness of the tape will depend on the size of the gap. Pre cleansed, degreased and dried fill the gap with clear silicone sealant.Next, cut a piece of tape, appropriate size and apply it liquid nails.Now you can stick the tape on top of the gap.It is necessary to wait at least a day before you start to use the bathroom.


All of the above methods of getting rid of the gap between the wall and the rim of the bath are suitable only if it is a small gap, the width of which does not exceed 3 cm. If you are dealing with a wide cleft,you'll have to stock up on finishing materials and float construction skills.

Terminate the gap can be using tiles. best to use the one that was left after the wall covering.If after repairing nothing left, just buy the white tiles of suitable size, such that it took a minimum of cutting.White tile will blend in with a white bathroom, provided that you have it because white and a border will be almost invisible.If the design of wall tiles you used decorative border, and then you can make the joint in the same border.
