Bathroom remodeling is one of the most popular home improvement projects in Riverside County — and with good reason. A well-executed bathroom upgrade adds real estate value, improves daily comfort, and can fix longstanding plumbing issues at the same time. Davis Plumbing and Heating Inc. provides rough-in plumbing, fixture installation, and drain/supply line work for bathroom remodels throughout Murrieta, Temecula, Menifee, and surrounding communities.

What Plumbing Work Is Typically Involved in a Bathroom Remodel?

  • Moving or replacing supply lines — Hot and cold water lines to the sink, toilet, shower, and tub may need to be relocated if the layout changes, or replaced if the existing pipes are old or corroded.
  • Drain reconfiguration — If moving a toilet, shower, or tub, the drain must be relocated and properly vented according to current plumbing code.
  • Shower valve installation — A new thermostatic or pressure-balancing shower valve provides better temperature control and safety.
  • Toilet replacement — Swap an old toilet for a modern WaterSense high-efficiency toilet that uses just 1.28 gallons per flush.
  • Vanity and sink installation — Davis Plumbing connects new vanity tops, vessel sinks, or undermount sinks to supply and drain lines.
  • Permits and inspection — Any changes to drain, waste, and vent (DWV) systems in Riverside County require a permit and inspection. Davis Plumbing handles the permit process for our customers.

Common Mistakes to Avoid in Bathroom Remodel Plumbing

  • Skipping permits — Unpermitted plumbing work can void your homeowner’s insurance, cause problems at sale, and result in costly correction work later.
  • Choosing the wrong drain slope — Horizontal drain lines must slope exactly 1/4 inch per foot of run. Too little slope causes clogs; too much can cause solids to be left behind.
  • Forgetting the vent — Every fixture drain must be properly vented to prevent siphoning traps and sewer gas infiltration. This is where DIY mistakes are most common.
  • Ignoring existing pipe condition — If your home has galvanized supply pipes, a remodel is the perfect time to replace them with copper or PEX before closing the walls back up.

Water-Saving Upgrades Worth Considering

A bathroom remodel is the ideal time to upgrade to water-efficient fixtures. WaterSense-labeled toilets, showerheads, and faucets can reduce bathroom water usage by 20–30%. In a dry region like Riverside County, every gallon counts — and your water bill will reflect the savings.
