Types Of Toilets And Space Requirements

Choosing the right toilet type for your bathroom involves considering space. Bathrooms come in all shapes and sizes.

Let’s explore toilet types and the space they need.

Standard Versus Compact Models

Toilets typically fall into two categories: standard and compact. Standard models are common in many homes.

They need more space. Compact models are perfect for small bathrooms. They save space without sacrificing comfort.

  • Standard toilets: length around 27-30 inches, width up to 20 inches, height near 27-32 inches.
  • Compact toilets: can reduce length by 2-6 inches compared to standard toilets.

Corner Toilets And Wall Hung Variants

Different types offer unique space solutions. Corner toilets fit into corners, freeing up floor space. Wall hung variants are mounted on the wall, making floor cleaning easy.

Model Space Required
Corner Toilets Generally, need less space than standard models
Wall Hung Toilets Leave space beneath; may require a strong wall for mounting


Measuring For Your Space

  • Tape measure – for length and width
  • Notepad and pencil – for recording measurements
  • Level – to ensure evenness

Step-by-step Guide To Measuring

Follow these steps:

  1. Clear the area around your toilet.
  2. Use the tape measure to find the wall-to-wall width.
  3. Record the widest point width.

Maximizing Bathroom Layout

Maximizing Bathroom Layout

Planning a bathroom means knowing the size of key elements. A toilet width matters for comfort and design. It’s vital for a functional space.

Strategic Positioning Of The Toilet

The toilet’s position affects bathroom flow. A toilet should not be the first thing seen upon entry. It’s best tucked away for privacy.

Generally, maintain at least 18 inches from the center of the toilet to any wall or fixture. This ensures comfortable use.

  • Corner toilets save space in small bathrooms.
  • Consider a wall-hung model for sleekness and easier cleaning.
  • Place toilets opposite the door for aesthetic appeal.

Integrating Storage Solutions

Smart storage keeps bathrooms tidy. Use cabinets and shelves wisely. Think vertical to maximize space.

Storage Type Advantages
Over-the-toilet cabinets Utilizes unused space, ideal for essentials
Recessed shelves Saves space, sleek look
Wall-mounted bins Flexible placement, easy access
  • Wall niches are great for extra storage without protrusions.
  • Use cabinet organizers to keep things in reach.

Other Dimensions To Consider

While the width of a toilet is a key factor, other dimensions play crucial roles in comfort and compliance.

Whether you’re renovating or installing a new bathroom, consider the height and depth of the toilet.

Height And Depth For Comfort

  • Comfort Height Toilets: Typically range from 17 to 19 inches from floor to seat top.
  • Standard Height Toilets: Usually measure about 15 inches from floor to seat top.
  • Depth: Generally spans between 27 and 30 inches from the wall to the toilet’s front.

Choosing the right height and depth ensures ease of use for all members of the household.

A toilet that’s too high or too low can be uncomfortable. Similarly, a toilet that’s too deep can make small bathrooms feel cramped.

Clearance And Code Compliance

Minimum Clearance Requirements
Direction Measurement Importance
Front Clearance At least 21 inches Allows for comfortable use and passage.
Side Clearance At least 15 inches Provides adequate elbow room.

Bathroom layouts must comply with local building codes to ensure safety and accessibility.

These codes specify distances from the toilet to walls and fixtures. Sufficient space allows for mobility and the use of amenities without restrictions.

Compliance with clearance regulations also future-proofs your bathroom for any potential renovations.
