Unless the architect or builder are prepared to guarantee the concrete and tile baptistry will not leak (and not need regrouting!) in under 10 (or 25) years, don’t bother!
Our fibreglass baptistries mean less fuss and cost at installation as the unit comes as a whole. Insulation is built in, the walls need no additional support, and the reinforced lids can take the whole choir! And our fibreglass baptistries need no maintenance for years to come. The baptistry is guaranteed for 10 years, though it will probably last well over 25 years.
Concrete pools are poorly insulated, if at all. Ours come with 50mm of insulation built in as standard. Heating the water in concrete and tile pools is expensive and wasteful as you end up heating the concrete as well as the water. The fibreglass lids can be put over the tank whilst filling and heating to keep in the heat and, unlike wood, will not swell and warp. Even treated timber starts to swell once the varnish wears.
GRP pools do not need maintenance (other than an occasional wipe down). The grouting between tiles soon attracts mould and we have phone calls from churches with leaky tiled baptistries at the rate of one a month. It isn’t just a false economy, it’s no saving at all to have a concrete and tile baptistry.
