Starting a Self Serve Car Wash

Lot Selection

A good rule of thumb to follow concerning lot sizing is 100'-120' deep x a minimum of 75' wide depending on the number of bays. (Typical 4 bay self-serve wash would need a lot 100'-120' deep x 100' wide minimum).
Good access from both directions of traffic flow is also very important.
Ideal traffic speed should be under 40 mph.
Lot size and shape will determine if you design a "Drive-in-back-out" or "Drive-through" building. (Income streams tend to favor the "drive-through" design).
Ideal locations are near residential areas, apartment complexes or busy traffic flow routes.
A good rule to follow regarding the cost of property is that the monthly lease payment should not exceed 15 - 20% of the gross monthly income of the wash.

Bay & Building Sizing

Ideal bay size is 16' wide x 28' long (inside measurements). Truck bays should be 17-18' wide and 28' long. (Smaller bays will work but are not recommended.)
Typical pump room is 10'-15' wide x 28' length.
Typical bay height is 10' for car bays and 12'-14' for truck bays.

Building Placement

Depending on specific codes your building should be placed on the lot to allow for 1-2 cars minimum to be "stacked" behind each bay waiting to wash. Vacuums can be placed in this area but should not impede the normal flow into the bays.
Make sure there are adequate drying and vacuuming areas that are out of the main traffic flow.
Ideally your bays should have a southern exposure to help reduce ice build-up in cold weather conditions.
Local codes will also have "set-back" requirements on building placement.

Inside Vs. Outside Bays

In many rural locations washes can be built with an open outside bay for trucks, trailers, tractors, etc.
However, as a rule an outside bay will bring in only about 40-50% of the revenue of an inside bay.
It is always better from a revenue standpoint to enclose all bays and build one larger if you feel you will have adequate truck traffic. This bay then can also be used for cars if other bays are busy.

Revenue Projections-Bays

Studies find that it takes a population base of 1000-1500 people to support 1 self-serve bay. ( A town of 5000 people could theoretically support a total of 5 self-serve bays between all competitors.)
At this population level the National Average is approximately * $1000 - 1500 per bay, per month of gross income for one self-serve bay. (This is an estimate average only, incomes can and do vary.)

Revenue Projections-Vacuums

The ideal number of vacuums to have is 1-1/2 vacuums per 1 bay of self-serve. (i.e., a 3- bay wash should have 4-5 vacuums placed somewhere on the lot).
National average of revenue per vacuum is approximately * $200 - 300 per vacuum per month in gross revenue. (Incomes can and will vary.)

Revenue Projections-Vending

National average of vending revenue is approximately * $350 - 400 per month gross revenue based on offering at least 4-5 different vending products. Revenue can be increased with multiple product, clear front vending machines.

Operating Cost Projections

Average operating costs (based on multiple sources) is approximately *53% of gross income which includes *13% for attendant labor which you may or may not need. *(Lease payments, income tax, debt reduction or depreciation are not included). These figures can and do vary by region.

Options & Features

Typical self-serve washes will offer hot wash, hot rinse-winter & cold rinse-summer, hot or cold wax, foamy brush and spot-free rinse.
An important new feature is "Spot-Free Rinse". This features increases revenue stream due to the fact that customers "buy" another cycle of time to get this feature. This means a potential double the income from each customer using this feature.
Tire Cleaner and Pre-soak systems are also options that increase customer satisfaction as well as income stream.
It is our strong recommendation that Instantaneous Tankless water heaters also be used in place of conventional water heaters. These heaters can reduce gas costs up to 40% vs. conventional heaters. (If it rains for a week, only the pilot is using gas on these type of heaters vs. conventional heaters which heat the water column continuously rain or shine).
Cold climate washes should also not be without a floor heat system. These systems reduce liability and increase customer satisfaction. In-floor circulating systems are most popular. However, above-head radiant tube heaters also give the benefit of heating the floor as well as the customer.
For floor heater sizing it is wise to also heat 3'-4' on the entrance and discharge aprons. This will reduce liability in the customer "walk" areas as they use bill changers and vending machines.
Bill changers are also a necessity. Studies have shown a minimum 10% increase in gross revenues in washes with changers. $1 & $5 changers are now the norm in all new wash facilities, with $10 & $20 optional.
Vending products such as towels, Armorall, window cleaner and fragrance trees should not be overlooked as an added revenue source. (Average vending per wash location is approximately * $350 - 400 (estimate only) per month in total gross revenue).
