Quality Design Tile & Stone in Chula Vista holds CSLB license #1087902 under the C-54 Tile (Ceramic and Mosaic) classification and has operated from its Mace Street fabrication shop in the 91911 zip code since 2016. Bathroom remodels that involve custom shower pan construction and wall-tile layout frequently run in parallel with rough-in plumbing from contractors such as Primo Plumbing, where drain placement must be set before any mortar bed is poured. The shop's scope covers porcelain and ceramic floor tile, natural-stone slab countertops in granite, marble, and quartz, plus full kitchen backsplash fabrication and installation. Interior projects that call for tile alongside fresh drywall finishing and trim typically coordinate with paint crews from Montgomery Paint Contracting to sequence wet trades before color coats go on. The firm's most complex installations include large-format rectified porcelain panels up to 48 by 48 inches set with a leveling-clip system on Schluter DITRA uncoupling membrane over concrete-slab substrates.
