About Spa Cover Shipping
Spa covers normally take about 3 - 6 weeks from the time of order to actual delivery (time varies by location). That's about a week and a half in production and seven days in transit. Spa Covers are shipped by LTL (Less Than Truckload), a tractor trailer, and require someone to accept and sign for the delivery. Please call us to order at 1.800.770.0292.

Spa Cover Production, Delivery and Return Policies


Voltage ratings for spa components can be confusing. Pump motors are listed as 115 or 230v,
whereas heater elements working in the same system are listed as either 120 or 240v.

Let's just say that any components listed as 110-120 volts are compatible
and any components listed as 220-240 volts are likewise compatible.

Plumbing Size

Refers to the inner diameter of the pipes used in your system (see diagram below).

Pipe Size

IMPORTANT! It's best to enter the INSIDE diameter of your pipe fittings here. However, if you taking your measurements from the wet end, A 3" overall OUTSIDE diameter translates to 2.0" plumbing size while a 2 3/8" OUTSIDE diameter translates to a 1.5" plumbing size.

Control Voltage

Is the power to your spa pack currently 120 V or 240V?


For some reason, pumps are usually rated at 115 or 230 volts instead of the more common 120 or 240 volt ratings.

Don't be concerned about this. 115 volt pumps work just fine in 120 Volt systems while 230 Volt pumps are at home in 240 volt systems.

Secondary Pump Circuit

If your spa has two main pumps (in addtion to a circ pump), indicate that here. The second circuit is wired for a 240 volt pump. If you need 120V, please contact us.
