Mark answers personally, usually the same day. Texting is fastest.

Choosing Finishes Together at Your Kitchen Table

Every home and family is different—so instead of pushing a one-size-fits-all material, Mark brings real samples right to your home.

  • You pick your exact finishes right at your kitchen table: compare full-height, easy-clean shower walls and vanity finishes in your own bathroom light.
  • Easy everyday care: we help you select non-porous surfaces, recessed storage niches, and slip-resistant shower floors that are simple to keep clean.
  • Built for real safety, never clinical: structural wood blocking inside the walls for grab bars and built-in benches that match your fixtures.

Tub-to-Shower Conversion

Swap a hard-to-step-over tub for an open, easy-entry walk-in shower. Best for: homes where stepping over a tub wall has become hard or risky. CDU-INC removes the tub and builds a low-threshold shower in the same space, usually without moving walls.

What's included

  • Tub removal and haul-away
  • Low-step shower pan and slip-resistant floor
  • Easy-to-clean wall surfaces and recessed storage niche chosen at your kitchen table
  • Updated shower valve and handheld shower head
  • Frameless glass door or open curtain layout
  • Structural wood blocking inside the walls for grab bars

Complete shower only: Mark doesn’t do grab bars or benches as separate small jobs. Doing the whole shower is how the waterproofing gets done right, start to finish.
