How to Choose a Commercial Toilet Suite
Choosing a toilet for a commercial bathroom starts with the plumbing and room layout, not simply the appearance of the toilet.
Commercial toilet suites may be installed in offices, schools, childcare centres, public amenities, healthcare facilities, aged-care environments, workplaces and other shared bathrooms. Depending on the project, the toilet may also need to suit accessible, ambulant or junior users.
Before ordering, check the pan outlet, set-out, water inlet, overall projection and any project-specific requirements. For refurbishment projects, measure the existing installation carefully before selecting a replacement.
For a complete commercial bathroom project, browse our Commercial & Care Bathroom Products to coordinate toilets with basins, grab rails, tapware and other washroom fixtures.
Start with the Pan Outlet: S-Trap or P-Trap
One of the most important details to confirm is how the toilet connects to the drainage.
An S-trap toilet connects to a waste outlet through the floor. The distance between the finished wall and the centre of the floor waste is generally referred to as the set-out.
A P-trap toilet connects to a waste outlet through the wall.
Some toilet suites can accommodate an S-trap installation through a supplied conversion bend or connector, while others are designed for a particular outlet arrangement.
Do not assume a toilet will fit simply because the overall dimensions look similar to the existing suite. Check the individual product specification and have the plumbing arrangement confirmed before ordering.
Measure the S-Trap Set-Out Carefully
For floor-outlet installations, the set-out can determine whether a toilet is suitable.
Measure from the finished wall surface to the centre of the floor waste. If tiles have not yet been installed, allow for the final wall finish when checking the measurement.
Commercial toilet models may support different set-out ranges, so compare your actual measurement with the manufacturer's specifications.
This becomes particularly important when replacing an existing toilet. Moving the waste pipe may involve additional plumbing work, so selecting a toilet compatible with the existing set-out can often simplify a refurbishment.
If you are unsure, provide your plumber with the toilet specification sheet before purchasing.
Check the Water Inlet Position
The toilet also needs a suitable water connection.
Depending on the model, the cistern may use a:
- Bottom inlet
- Back inlet
- Top/back inlet
- Concealed connection
The existing water point is especially important in renovation projects.
Changing from one inlet arrangement to another may require plumbing alterations, so compare the existing water supply position with the new toilet specification before ordering.
Where pipework is still being roughed in for a new project, finalise the toilet model early enough for the plumber to position the water and waste connections correctly.
Consider the Pan Projection and Available Space
Pan projection refers to approximately how far the toilet extends from the finished wall into the room.
This dimension can have a significant impact on commercial bathroom planning.
A more compact toilet may help where space is limited, while accessible or specialised toilet configurations may have a greater overall projection to suit the intended layout.
Before ordering, compare the toilet dimensions with:
- Bathroom partitions
- Doors and door swings
- Basins
- Grab rails
- Circulation space
- Toilet roll holders
- Backrests
- Other fixtures
Do not select the toilet in isolation from the rest of the bathroom.
Accessible and Ambulant Toilets Are Different
Accessible and ambulant bathrooms can have different layouts, fixture positions and toilet requirements.
An accessible toilet may form part of a larger accessible sanitary facility involving particular pan positioning, seat height, circulation space, backrest, grab rails and other fixtures.
An ambulant toilet is a different type of facility and can require a different arrangement.
For this reason, a toilet marketed for accessible or ambulant use should not automatically be assumed to make the complete bathroom compliant.
Always check the complete layout against the architectural drawings, project specification and applicable requirements.
When planning these bathrooms, coordinate the toilet with our Commercial Grab Rails and other care bathroom products rather than selecting each item independently.
Coordinate the Toilet with Grab Rails and Backrests
In accessible and care bathrooms, the relationship between the toilet and surrounding support products is particularly important.
Before confirming the toilet, check the proposed position of:
- Side grab rails
- Rear grab rails
- Folding support rails
- Backrest
- Toilet roll holder
- Basin
- Door
- Other support accessories
A change in pan projection or toilet position can affect the location of several other fixtures.
Where a backrest or support arm is specified, check compatibility and mounting requirements separately.
The wall structure should also be prepared for any grab rails or support fixtures before finishing work is completed.
Back-to-Wall, Link and In-Wall Toilet Configurations
Commercial toilet projects can use several different configurations.
Back-to-wall toilets position the rear of the pan close to the wall, creating a relatively clean and compact installation.
Link toilet suites use a separate cistern connected to the pan and can offer flexibility for some replacement or commercial applications.
In-wall cistern toilets conceal the cistern within the wall or service cavity. This can provide a streamlined appearance but requires additional planning for the cistern frame, plumbing, flush plate and future servicing access.
The most suitable configuration depends on the plumbing, available space, wall construction and project specification.
Consider Junior Toilets for Children's Facilities
Childcare, early-learning and some education projects may require fixtures designed around younger users.
Junior toilet suites can provide different pan dimensions and heights compared with standard adult toilets.
However, product selection should still be based on the specific facility and project documentation.
For childcare projects, coordinate the toilet with suitable basins, tapware and other Commercial & Care Bathroom Products rather than adapting an adult bathroom layout without checking the requirements.
Rimless or Traditional Flush Design?
Commercial toilet suites may use different flushing designs.
A rimless toilet removes much of the traditional enclosed rim around the bowl, which can provide easier access to the bowl surface during cleaning.
Traditional or box-rim toilets use a different flushing arrangement and may still be specified for particular projects or replacement applications.
When comparing toilets, also check:
- WELS rating and flush volumes
- Cistern compatibility
- Included seat
- Soft-close function where applicable
- Flush mechanism
- Replacement part availability
- Manufacturer warranty
For high-use commercial facilities, ongoing cleaning and servicing can be just as important as the initial purchase price.
Check What Is Included with the Toilet Suite
Not every commercial toilet listing includes exactly the same components.
Before ordering, confirm whether the product includes:
- Toilet pan
- Cistern
- Toilet seat
- Connector or conversion bend
- Flush button or flush plate
- Fixing components
- In-wall cistern where applicable
- Backrest or grab rails where required
Do not assume accessories shown in product photography are automatically included.
This is particularly important with in-wall toilet systems, accessible toilets and commercial project products where components may be specified separately.
Replacing an Existing Commercial Toilet
For replacement projects, record as much information as possible before removing the existing toilet.
Check:
- S-trap or P-trap
- Existing set-out
- Water inlet position
- Pan width and projection
- Available wall space
- Cistern position
- Nearby partitions
- Existing grab rails and accessories
Photos with a tape measure can also be useful when comparing replacement options.
If the existing plumbing is unusual, ask your plumber to confirm whether the proposed toilet can be installed before ordering.
What to Check Before Ordering a Commercial Toilet
Before confirming your order, check:
- S-trap or P-trap outlet
- S-trap set-out where applicable
- Water inlet position
- Overall pan projection
- Toilet width and height
- Cistern configuration
- Required seat height
- Accessible, ambulant, junior or general commercial application
- Grab rail and backrest locations
- Door and partition clearances
- Included and separately required components
- WELS and product specifications
- Existing plumbing for replacement installations
- Project drawings and specifications
Confirming these details before ordering can help avoid plumbing changes, incorrect product selection and installation delays.
