Sun-Mar™ high-capacity self-contained composting toilet

Sun-Mar™ | Excel 240

A powered self-contained composting toilet for three to four people full-time and up to seven people in part-time or holiday use.

Excel 240 provides greater capacity than the smaller Sun-Mar™ on-floor models while retaining a completely self-contained bathroom installation.

Full-time

3–4 People

Stated system capacity

Part-time

Up to 7

Holiday or intermittent use

Format

On Floor

High-capacity self-contained unit

Technology

BioDrum™

Staged composting process

Product background

Higher capacity without an underfloor chamber

Excel 240 is designed where higher user numbers need to be managed within a self-contained bathroom installation.

It provides a larger on-floor pathway than Spacesaver or Compact while retaining Sun-Mar™ BioDrum™ composting and staged processing within the toilet.

How it works

Compost, evaporate and finish within one unit

Stage 1 Compost

Waste and bulking material enter the BioDrum™, where rotation mixes and aerates the composting material.

Stage 2 Evaporate

Powered ventilation and the system's evaporation pathway help manage liquid while the emergency drain provides overflow protection.

Stage 3 Finish

Compost moves from the active composting stage into the finishing drawer before final removal.

Core product details

Established Sun-Mar™ self-contained design

Patented BioDrum™ technology for staged composting.
High-capacity self-contained design.
2-inch vent attached at the top rear of the unit.
1-inch emergency drain fitted at the rear for overflow protection.
Detachable footrest provides easier finishing-drawer access.
Designed for installations with reliable electrical power.

Best suited for

Homes, larger baches and higher-use cabins

Excel 240 suits homes, cottages, cabins, sleep-outs, baches and selected light-commercial applications where a larger self-contained toilet is preferred.

Capacity note: system capacity should be matched to the actual average user load rather than occasional short-term peaks.

Certification

NSF performance and electrical certification

NSF/ANSI 41 — Non-Liquid Saturated Treatment Systems

The supplied Sun-Mar™ product information identifies independent maximum-capacity testing for odour performance and finished compost.

Sun-Mar™ electrical features are identified as CSA certified under file number LR55925.

NSF: What you need to know about composting toilets

Starter materials are not included.

Use Sun Mix 40 Green with Microbiota MicrobeBURST™ and Nature Flush enzymatic cleaner .

WCTNZ® is an authorised New Zealand supplier of Sun-Mar™ composting toilet systems. Local support is available for system selection, installation information, consumables and after-sales requirements.

On-floor or split system?

Excel keeps the composting process within the toilet itself. Where suitable underfloor space is available, a Centrex split system provides a separate composting chamber and a different servicing pathway.

Before you choose, think:

1. Your place — tiny home, bach, family home, RV, or public site

2. Your building — whether it suits a self-contained or split composting toilet system

3. Your needs — user numbers, maintenance preferences, and how off-grid you want to be

To narrow it down properly, start with the Composting Toilet Guide .
