Toilet and camp supply calculator
The first answer is an awkward one: for Saxony there is no table. The Saxon assembly venue regulation requires in § 12 "a sufficient number of toilets" and fixes exactly one figure — at least one step-free accessible toilet per ten wheelchair spaces. Older versions of the model regulation carried a ratio per 100 visitor places, and contradictory versions of it still circulate online.
So this tool computes two things separately: the one figure that is prescribed, and the planning you are responsible for. The ratios are inputs with starting values, not standards — you can and should adapt them to your audience. For multi-day camps it adds showers, fresh water, servicing intervals and waste volume, which no rental company's calculator covers.
If you are also cooking for these people, the quantities are in the Camp kitchen calculator — fresh water and waste show up there too.
Prescribed
0 step-free accessible toilets
SächsVStättVO § 12 Abs. 2
Beyond that, SächsVStättVO § 12 prescribes no number but "a sufficient number". What follows is your planning, not the law.
Your planning
- Toilets, women: 3
- Toilets, men: 2
- Urinals: 2
- Washbasins: 3
- Demand factor from duration and alcohol: 1.44
How this is calculated
Prescribed under SächsVStättVO § 12 Abs. 2 is at least one step-free accessible toilet per ten wheelchair spaces. That is the only fixed number in the section; everything else is "sufficient", and therefore a planning decision the authority may pin down case by case.
Planning uses a demand factor: base demand up to four hours, ten per cent more for each further hour, and twenty per cent on top where alcohol is served. The factor is visible in the calculator, so nobody has to trust a curve they cannot see.
The gender split is asked for because urinals only serve part of the crowd. What they do not cover, cubicles have to carry — so both sides are calculated separately rather than through a blended figure.
For camps: fresh water and waste per person per day, showers by head count, and the servicing interval from the number of uses per toilet. Everything rounds up — half a cubicle serves nobody.
- SächsVStättVO § 12 — toilet facilities (the only binding figure)
- Ratios: experience values from our own event practice, adjustable in the calculator
Every figure with its source and review date is in the metrics register — including when it was last checked against the regulation.
Common questions
Because in Saxony there is none. § 12 requires "a sufficient number". Figures circulating online as the model regulation's ratio contradict each other, because they come from different states and different years. Presenting one of them here as law would be convenient and wrong.
Exactly what this calculator outputs: the ratio you planned with, how long the event runs, whether alcohol is served, and how many units that comes to. A calculation someone can follow is precisely what makes "sufficient" demonstrable.
The starting value is one toilet per 100 people for an event of up to four hours. For audiences that stay long, heavy drinks sales or families with children, plan tighter. Ask your rental company — they know experience values for your type of event.
The assembly venue regulation usually does not reach it at all. For multi-day camps other figures matter anyway: showers, drinking water, servicing rhythm and waste. That is what the second part of the calculator is for.

Orientation value. This calculator is no substitute for talking to the licensing authority, the building inspectorate, the fire service or a qualified planner. The German states each adapt the model regulation, so what binds your event is your state's version plus the conditions in your own permit.
