How Many Square Feet Is a 5x10 Bathroom?

Before we talk costs, let’s clarify: a 5x10 bathroom equals 50 square feet. This size is considered a standard full bathroom  large enough to include a combination tub/shower, a toilet, and a single-sink vanity.

It’s common in many raised ranch, split-level, or older homes, and often serves as a family bath or guest bath. In many remodels, homeowners want to modernize these spaces while optimizing layout, storage, and lighting.

What’s the Average 5x10 Bathroom Remodel Cost?

The cost to remodel a 5x10 bathroom depends on the finish level, layout changes, and your location. In Southern California, where materials and labor are slightly higher than the national average, here’s what to expect:

Factors like relocating plumbing, choosing luxury tile, or installing custom vanities can quickly increase costs. However, smart design choices in a compact 50-square-foot space can stretch your budget a long way.

Labor and Material Cost Breakdown

Here’s a breakdown of typical labor and material percentages for a 5x10 bathroom remodel cost:

Labor in San Diego and Oceanside averages between $80–$125/hour, depending on the trade. Hiring licensed professionals ensures your remodel is up to code and permits are properly handled.

Budgeting Advice: Follow the 30% Rule

When planning your remodel, always apply the 30% cushion rule. This means you should set aside 30% of your total budget to handle unexpected costs like water damage, outdated plumbing, or upgrading materials during the remodel.

For example, if your goal is to spend $20,000, plan your main expenses around $14,000 and reserve $6,000 for contingencies. Many homeowners find they use at least part of that cushion especially in older homes with hidden issues behind walls or under floors.

Size-Based Remodel Pricing: Small vs. Medium vs. Large

While we’re focused on 5x10 bathrooms, it helps to understand how remodel pricing scales based on size:

Medium-sized bathrooms like the 5x10 layout are ideal for full remodels not too small to limit design but compact enough to keep material and labor costs manageable.

Features That Influence the 5x10 Bathroom Remodel Cost

Several decisions can significantly impact your remodel cost:

1. Plumbing Relocation

Moving a toilet or converting a tub to a walk-in shower? That alone can add $1,500 to $3,500+.

2. Custom Vanities or Built-ins

Prefabricated vanities are affordable, but custom pieces can double the cost. They do, however, add functionality and a high-end feel.

3. Tile Choices

Standard ceramic tile costs about $3–$7 per sq ft, but glass, natural stone, or designer porcelain can reach $15–$30+ per sq ft.

4. Shower Upgrades

Frameless glass enclosures, rainfall showerheads, and niches add beauty and cost. Expect to pay $2,000–$5,000 for a luxury shower setup.

5. Permit and Inspection Fees

In San Diego County, bathroom remodel permits range from $200 to $1,000+, depending on scope.

Design Tips to Maximize a 5x10 Bathroom

Even a small bathroom can feel luxurious with the right layout and materials. Here’s how we make 50 square feet look and feel amazing:

• Use large format tiles: Fewer grout lines = bigger visual space

• Install a floating vanity: Creates the illusion of space and easy cleaning

• Opt for a clear glass shower enclosure: Keeps sightlines open

• Add recessed wall niches: For shampoo and soap storage without clutter

• Incorporate vertical storage: Like tower cabinets or over-the-toilet shelving
