This is a genuine, original manufacturer kit — not an aftermarket substitute — so you get the fit, function, and durability your spa was designed for.
Why spa owners choose this kit
One retrofit, total compatibility. Whether your original system used a TP800 or an older control panel entirely, this kit bridges the gap with the current TP700 topside.
Built for heavy-duty use. With support for three pumps, a blower, and a dedicated circ pump, it's suited to spas with higher equipment demands.
Future-proofed. BBA capability means you can add WiFi control down the line without replacing the whole system again.
No guesswork. Free shipping and clear part cross-references take the confusion out of hot tub repair.

Frequently asked questions
Is this a genuine manufacturer part?
Yes. The MXBP20 Retrofit Kit T8 is a genuine, original replacement kit, not a generic aftermarket clone.
My spa originally came with a TP800 panel. Will this kit still fit?
Yes. The TP800 has been discontinued and replaced industry-wide by the TP700. This kit includes the TP700 with a matching overlay, and a bezel (110574) is available separately if your original panel cutout is larger than the new one requires.
How many pumps and accessories can this system run?
Up to three pumps, a blower, and a dedicated 24-hour circulation pump. If your spa doesn't have a separate circ pump and instead relies on pump 1 for circulation, kit 110239 may be the better fit.
Can I add WiFi control to this system?
Yes. The control pack is BBA-ready, so you can add the optional 59303 WiFi module now or later.
What if I can't find my exact part number?
Send us a photo of your existing control pack, panel, or spa data plate, along with your spa's make, model, and serial number, and we'll confirm the correct match.
