If you own, run or develop holiday parks, farming or seasonal worker accommodation, you know how important reliable bathroom and laundry facilities are. But what about how you build them? Or how much they are?

That’s where prefab ablution blocks come in. They offer a quick, cost-certain solution – without the disruption of traditional construction. 

Advance Build has 17+ years’ experience delivering high-quality, durable prefab buildings across New Zealand. And, when it comes to prefab ablution blocks, their carefully designed layouts help businesses create comfortable, efficient spaces for guests and workers.

So whether you need a small toilet block or extensive facilities, this blog is for you. It will guide you through your prefab options, help you understand what’s ahead and provide insights into the costs you’ll need to consider.

What are prefab ablution blocks?

Prefab ablution blocks are built offsite. Once completed, they are delivered to site and connected to their foundations.

They include facilities such as:

• Toilets
• Washrooms
• Showers
• Kitchens
• Laundries.

But, not all prefab blocks are created equal. While some prefabrication companies build outside, all Advance Build construction happens inside their controlled factory environment. This approach eliminates weather delays, tightens timelines and provides a precise, quality build each and every time. 

That’s why prefab ablution blocks are a popular choice for:

• Holiday parks + campgrounds needing modern, long-lasting guest facilities
• RSE (Recognised Seasonal Employer) worker accommodation that calls for comfortable and hygienic shared spaces
• Rural / farm sites who provide staff amenities in remote locations. 

But why, exactly, do prefab blocks appeal to operators? It mostly comes down to their practical advantages.

Prefab ablution blocks are:

• Quick to install (with minimal onsite disruption)
• Easy to maintain
• Built to withstand heavy use. 

Which prefab ablution block is right for you?

The ablution block you build will depend on the size and requirements of your site. Smaller sites, for example, might opt for a basic toilet and basin setup. Larger places will generally need a complete facilities solution incorporating bathroom, kitchen and laundry amenities.

Basic amenity units: prefab toilet blocks

For smaller sites or tighter budgets, a prefab toilet block is often the best choice. These compact units include the essentials (typically toilets and basins) in a simple, functional layout. 

They are ideal for:

• Holiday parks or campgrounds with limited guest capacity
• Seasonal or RSE worker accommodation 
• Remote properties needing low-maintenance facilities.

Despite their simplicity, Advance Build’s prefab toilet blocks are constructed to the same high standards as larger projects. Each unit is durable, hygienic and designed to handle regular use – with a clean, modern finish. 

Complete solutions: prefabricated ablution blocks

At the other end of the spectrum, larger sites usually need an all-in-one solution. This generally means prefabricated toilet and shower blocks, together with kitchen and laundry facilities. 

These comprehensive setups include amenities such as:

• Toilets + showers
• Basins
• Lighting
• Ventilation
• Accessible cubicles
• Laundry areas (including sinks + washing machines)
• Kitchen zones for meal prep + cleaning.

They are well suited to:

• Holiday parks or campgrounds with plenty of guest capacity
• RSE worker accommodation where full facilities are needed
• Rural developments in remote locations, away from other services and amenities.

What affects the cost of prefab ablution blocks?

When planning your project, it’s natural to ask: how much will a prefab ablution block cost? The answer depends on a few key factors. 

Here are some of the main elements influencing cost:

• Size + configuration – The number of cubicles, showers and basins will affect pricing. Larger blocks with more facilities cost more to build and install.
• Fitout + inclusions – Adding extras (e.g. higher-end finishes) will increase the overall cost.
• Accessibility requirements – Unisex or wheelchair-accessible facilities require extra space, wider doorways and specialised fittings (e.g. grab rails) to meet NZ Building Code Standards. These added features can impact your budget.
• Site conditions + connections – Your total cost will vary depending on the location of your site and how easily services like water, power and wastewater can be connected. 
• Compliance + infrastructure upgrades – Sometimes, a new ablution block will need upgrades to existing systems (e.g. wastewater capacity or stormwater management).
• Transport + installation – Delivery distance, site access and foundation work all play a part in your final pricing. 

As you can see, the prefab building itself is often just one part of the total cost. That’s why it’s important to engage an experienced team like Advance Build right from the start.

• Assess your site
