Coastal Kasa, a women-owned interior redesign and residential painting studio in Carlsbad, specializes in kitchen and bathroom transformations from its Loker Avenue East office near the Poinsettia corridor. Kitchen redesigns encompass cabinet refacing, hardware upgrades, and backsplash installation—projects where relocated supply lines and drain adjustments require plumbing coordination from contractors including MasterCraft Plumbers. The team holds color-theory certification and applies the psychology of color to residential palette selection, guiding homeowners through undertone analysis before any primer coat is applied. Bathroom scope covers vanity replacement, tile accent walls, fixture swaps, and lighting upgrades, all managed under a single project timeline that eliminates multi-vendor scheduling gaps. Electrical modifications for under-cabinet LED strips, dimmer switches, and GFCI outlet relocations during kitchen renovations run through licensed electricians including Wheyland Electric, maintaining Title 24 compliance on every circuit change. The studio's highest-spec kitchen projects include full backsplash demolition and replacement with hand-cut porcelain mosaic tile over Schluter DITRA uncoupling membrane, preventing lippage across substrates exceeding 1/8-inch variation.
