Do Coliving Spaces Have Private Bathrooms? The Answer Is a Regulation, Not a Preference

Most coliving rooms share a bathroom. En-suite rooms exist, they are usually the most expensive rooms in the building, and they are more common in purpose-built schemes than in converted houses — because retrofitting drainage into a Victorian terrace is expensive in a way that designing it into a new building is not.

What matters more than the label is the ratio, and it is worth asking for the number rather than the adjective. "Shared bathroom" in a house with one bathroom for eight people is a materially different product from "shared bathroom" in a house with three bathrooms for eight. Both are advertised the same way.

Ask two questions on a viewing: how many people share this specific bathroom, and is there a second toilet separate from the shower room. The second question matters more than people expect, because morning congestion in shared housing is almost always about the toilet rather than the shower.

Toronto's multi-tenant house framework, in force since 31 March 2024, requires at least one bathroom — a sink, a toilet, and a bathtub or shower — for every four dwelling rooms. That is a licence condition, not a guideline.

Read it from the operator's side and it stops being a comfort standard and becomes an arithmetic constraint. Your lawful maximum room count is the number of compliant bathrooms the building has, or can realistically gain, multiplied by four. A house whose floor plan shows eight lettable rooms needs two compliant bathrooms before eight rooms are legal.

This is the single most common way a Toronto acquisition model turns out to be wrong after the offer. Adding a bathroom is not a fit-out line item — it is a drainage problem with a construction cost and, depending on the building, a structural one. Work the ratio backwards before you offer: count the compliant bathrooms, multiply by four, and model the revenue on that number rather than on the floor plan.

The framework came with genuine liberalisation attached — multi-tenant houses are now permitted across the whole city rather than in selected former municipalities. The trade was supply for oversight, and the bathroom ratio is one of the places the oversight bites.

England does not set a single national bathroom ratio for HMOs in the way Toronto does. What it sets nationally is minimum sleeping room floor areas, as mandatory licence conditions since 1 October 2018: 6.51 square metres for one person aged over 10, 10.22 square metres for two, and 4.64 square metres for a child under 10. A room below the threshold cannot be licensed as sleeping accommodation, whatever the building is called.

Amenity standards including bathroom provision are set locally, through licence conditions and council HMO amenity standards, which is why they differ between authorities. That local variation is real and it is checkable: the council publishes its standards, and the licence you are issued carries the conditions you are held to.

The practical consequence for an operator is the same as Toronto's even though the mechanism is different. Two separate constraints — room size nationally, amenity provision locally — sit between the floor plan and the lawful bed count, and both are settled before you let a single room. Our own diligence sequence puts both of them ahead of any financial modelling, because a model built on the floor plan is a model of a building you are not allowed to operate.

Operators consistently overestimate the premium an en-suite commands and underestimate what it costs to provide. The room is smaller for the same footprint once the bathroom is carved out of it, the construction cost is real, and the maintenance surface area of the building goes up with every additional wet room.

In the buildings we have run, the honest position is that en-suite rooms let faster rather than let dearer. That distinction matters: faster letting shows up in reduced void days and lower turnover cost, which is genuine value, but it is a different line in the model from a rate premium and it should not be booked as one.

Where the en-suite premium is clearly worth it is the top room in a house — the one you use to anchor the rent card. A building where every room costs the same has no anchor and no ladder, and the good rooms let first while the weaker ones sit at a price nobody accepts. Spread your rates by what genuinely differs, and bathroom access is one of the few differences residents price consistently.

The reverse is also true and less often said: a shared bathroom at a good ratio, kept properly clean, outperforms a poor en-suite. Residents notice the cleaning schedule more than the door.

Where regulation sets a floor, treat it as a floor rather than a target. Toronto's one-per-four is the minimum a licence permits, not the ratio at which a house runs smoothly.

Our own planning assumption, from operating shared houses rather than from any published standard, is that one bathroom per three residents is where morning congestion stops generating complaints, and that a separate toilet is worth more than a second full bathroom at the same cost. Complaints about bathrooms are rarely about the shower — they are about the queue.

This is also a retention argument rather than an acquisition one. Bathroom ratio does not sell a room on a viewing; it decides whether the resident renews at the end of the term. Renewals are the cheapest occupancy points in the business, which makes the ratio a commercial decision that gets made once, at design or acquisition, and cannot be fixed with marketing afterwards.

For a resident: how many people share this specific bathroom, whether there is a separate toilet, and what the cleaning schedule for shared areas actually is — frequency, and what the cleaner does and does not do.

For an operator: the local amenity standard and any bathroom ratio in the licence conditions, the number of compliant bathrooms the building has now, what it would genuinely cost to add one, and the lawful bed count that falls out of those answers. Model that number, not the floor plan.

Both lists are short, and in both cases the answer is a number rather than an adjective. That is the point of the question.
