Budgeting Advice: The 30% Rule

Not sure how to set a realistic budget? Use the 30% rule as your guide.

 Spend no more than 30% of your bathroom remodel budget on aesthetic finishes.
The rest should go toward structural updates, plumbing, waterproofing, and ventilation things that matter most in the long run.

Break it down like this:

• 30%: Aesthetics (tile, paint, hardware, mirrors)

• 40%: Plumbing and electrical

• 20%: Fixtures and appliances

• 10%: Contingency buffer

 What Affects the Cost of a 5x8 Bathroom Remodel?

Several factors will influence your final price tag:

1. Material Quality

Luxury tiles, quartz countertops, and high-end vanities will drive up the budget. Budget-friendly alternatives like porcelain and laminate can keep costs down.

2. Fixture Upgrades

Switching from a tub to a walk-in shower, or installing a floating vanity, increases plumbing and labor costs.

3. Layout Changes

Rearranging the location of the toilet or shower requires permits and added plumbing expect an extra $1,000–$3,000.

4. Custom Features

Heated floors, rainfall showers, or integrated lighting systems all add cost but can elevate your bathroom’s function and resale value.

5. Permits and Inspections

In San Diego County, permits can range from $500–$1,200 depending on the scope of work.
