Travertine in showers is an excellent choice with proper care and proper sealing. Cleaning and removing Mineral and Hard Water build up can be completed before sealing process.
Travertine for your shower is an excellent choice as long as it installed correctly and sealed. The shower floors do have an affinity for foot oils, and conditioner residues that can build up if not maintained properly. With the right detergents and tools this can easily be cleaned and refinished to original or better condition.
Repairing any cracks and holes, sealing with a quality impregnating sealer, and using a squeegee to dry after showering, as I recommend for all shower enclosures, will keep your Travertine shower looking good for years. We also offer yearly maintenance cleanings if professional help is needed.
