Yes! The Trelino Evo models can be kept in wet conditions as they are made of plastic and won’t be prone to mold or warp. The Trelino Origin options have wooden lids but can also be used in the wet bath. However, the lids should have a finishing oil applied beforehand to make them more water resistant. For each model, we do recommend that the toilets are given time to dry so that there is no mildew buildup around them.
