The interior of the pool, or vessel of the pool, is as important as the pool coping or the terrace. It is important to choose well the material to place. The new pools are covered with porcelain tiles, for the durability, easy installation and aesthetic properties. The ceramic material is resistant to the chemical products used in the maintenance of the pool and has no problems of falling pieces as occurs with the gresite, offering a great advantage. To facilitate the use of clean funds, Ceramica Mayor has developed a system of cove pool and cove pool corners and angles, to be able to finish all the areas of corners and right angles and turning them into curves, to improve the cleaning and facilitate the completions of benches and solarium of the pools. The half-round pieces of porcelain stoneware provide continuity between the pool wall and the pool floor while facilitating the cleaning of the pool cleaner. They can also be placed to round off any edge and 90-degree angle for greater integration, also facilitating cleaning in these areas and to create rest areas within the pool or "spa" areas.
