We are converting a tub to a tub/shower combination and want to put solid wall panels rather than tile. Is anyone familiar with Bertch panels or with Sentrel panels and have an opinion about them? We installed Swanstone panels in our downstairs shower last year and have been happy with it. But the size of our space in the bathroom we are working on now will require custom cut panels. The Bertch product will still require a seam on the back panel and I'm not sure I like that. the Sentrel product won't require a seam but I am not at all familiar with the product and haven't been able to find reviews of it.
Any advice?
