Step-by-Step Guide to Designing a One Piece Closet

Designing a one piece closet is about more than just choosing a toilet. It’s about creating a functional, stylish, and efficient element that matches your bathroom’s design while ensuring comfort and hygiene. Whether you're renovating a bathroom or starting from scratch, here's a clear, step-by-step breakdown to help you design a one piece closet that works beautifully and lasts for years.

Step 1: Understand What a One Piece Closet Is

A one piece closet integrates the tank and bowl into a single, seamless unit. Unlike two-piece toilets, this design minimizes joints and gaps where dirt and bacteria can collect. The result is easier cleaning and a sleeker appearance.

It’s also heavier and slightly more expensive than traditional two-piece designs, but worth the investment for anyone who values low-maintenance cleanliness and a modern look.

Step 2: Assess Your Bathroom Layout

Before you pick a closet, understand the dimensions and plumbing layout of your bathroom. Focus on:

• Rough-in size: This is the distance from the wall to the center of the toilet drain. Most toilets have a 12-inch rough-in, but it’s essential to measure yours before choosing a model.
• Available space: A one piece closet typically takes up slightly more floor space at the base, though it can be more compact in height. Make sure there’s enough clearance around it for comfortable use.
• Drain type: Floor or wall-mounted drains will influence your closet options.

Step 3: Choose a Design That Fits Your Aesthetic

The design of your one piece closet should match your bathroom’s overall style. Whether you lean modern, minimalist, or classic, there are designs to match. Consider:

• Shape of the bowl: Round bowls are compact and space-saving, while elongated bowls offer more comfort.
• Color: While white is the go-to for most sanitaryware, many sanitaryware manufacturers now offer off-white, matte black, and other custom colors.
• Finish: A smooth glaze helps prevent stains and bacteria buildup. Some brands offer advanced nano-coatings for extra hygiene.

Step 4: Select the Right Features

Modern one piece closets come with features that go beyond basic functionality:

• Dual flush systems: Save water with separate flush options for liquid and solid waste.
• Soft-close seat covers: Prevent loud slams and extend the life of the seat.
• Anti-bacterial seats and rimless design: Enhance cleanliness and reduce the need for harsh cleaning chemicals.
• Eco-friendly certification: Look for models that are rated for water efficiency.

Some of the best sanitaryware brands offer one piece closets that include integrated bidets, night lights, and heated seats for added comfort.

Step 5: Check Compatibility with Sanitaryware

Make sure the closet you select works well with other bathroom fittings like wash basins, bidets, and urinals. A mismatch in design or finish can ruin the cohesion of your bathroom. Consider buying from the same sanitaryware manufacturer to ensure visual and functional consistency.

Also, verify that the product complies with plumbing and building codes in your region.

Step 6: Focus on Durability and Maintenance

Not all one piece closets are made equal. Look at:

• Material quality: High-grade ceramic or vitreous china ensures durability.
• Warranty: Top brands offer multi-year warranties, indicating confidence in their product’s longevity.
• Ease of cleaning: Seamless design reduces hard-to-reach areas where mold or grime can build up.

Ask about availability of replacement parts. A minor component failure shouldn't mean replacing the entire unit.

Step 7: Get Professional Installation

Even if you’re handy with tools, it’s wise to get professional installation. One piece closets are heavier and trickier to install due to their integrated design. Improper installation can lead to leaks or poor performance.

An experienced installer ensures correct placement, secure sealing, and proper connection to the plumbing line. They’ll also test for water flow and flush power before wrapping up.

Step 8: Regular Maintenance Tips

After installation, maintain your closet to preserve its look and performance:

• Clean weekly using mild, non-abrasive cleaners.
• Check flush mechanisms periodically to ensure they’re working efficiently.
• Inspect seals and joints annually for any wear or minor leaks.

Avoid using strong chemicals or acidic cleaners that may corrode parts of the toilet or damage the glaze.

Bonus: Smart Shopping Tips

When shopping online or in stores, keep these points in mind:

• Read reviews and compare models before buying.
• Stick to best sanitaryware brands with a proven track record.
• Check delivery options and return policies.
• If shopping online from a site like Grepl Group, verify product specs and installation guides.
