Today’s first caller had a representative from NuLux come do a consult at her condo, so she wanted designer Dean's expert opinion on the grout-free tile materials the company uses in bathrooms. 

Our next caller is having a plumbing issue; she had a cartridge replaced in her shower and now is getting only warm water there, likely due to a crossover according to several plumbers she’s spoken to. What’s up with that? 

Next up, a caller was wondering about installing a graywater system so she could water her garden using the water from her washing machine and dishwasher.
