Snorkel Hot Tubs HashTub Pleb

A handcrafted cedar hot tub from Snorkel Hot Tubs of Seattle, heated by a bitcoin miner sealed in dielectric fluid inside an immersion heat system that Hashrate House designs and assembles in the USA. The Pleb version uses an Antminer S19k Pro (120 TH/s at 24 J/TH, about 2.9 kW) to keep the water at up to 40 °C (104 °F), with the tub's 5.5 kW electric heater as backup. Snorkel lists the Pleb heat system at $4,395 (Hashrate House says $3,895), plus $12,265 to $22,940 for the tub and options; you join a paid waitlist for a design consultation, then pay a 50% deposit to order.

*What a pool would pay on average at today's difficulty, block reward and bitcoin price, before pool fees. Solo miners usually earn nothing, and very rarely a whole block. A plain electric heater turns the same electricity into the same heat, so the mining income is what makes the difference.

Payback is how long the bitcoin a device earns takes to add up to its price. It leaves out electricity, which buys the heat: compare earnings per kWh with your electricity price to see whether mining alone covers it. It uses the average of the last 3 months, to 12 Nov 2026: bitcoin at $79,558, 969 EH/s on the network and 3.15 BTC a block, less a 2% pool fee, for the hours you set. It cuts the block subsidy in half at each halving, the next around Apr 2028, and otherwise assumes those carry on unchanged, which they won't. Income at today's difficulty and price is about 17% below that average. Hashrate usually rises, though miners that stop paying after a halving may switch off, which leaves more for the rest. How we work it out.

Sources and data notes

Not yet confirmed from the maker's own documents: hashrate (120 TH/s and the Antminer S19k Pro come from Hashrate House's heat calculator preset; Snorkel's page gives no miner, kW or TH/s, but on Nostr on 30 April 2026 Snorkel said the S19 in its floor unit ran at 110–120 TH/s and confirmed 24 J/TH); power (2.88 kW from the calculator preset; Hashrate House's spec table and manual say ~4 kW from the miner; the Heatpunk Summit demo tub ran two S19j Pro at ~8 kW); store listings (Snorkel lists the Pleb heat system at $4,395 on hashtub.snorkel.com, a page that has not changed since 24 April 2026 according to its Last-Modified header; Hashrate House lists it at $3,895 on its live page and in its schema.org offer data, which sends buyers to Snorkel; no outside source settles which price is current); noise (Hashrate House's general 'below 30 dB' claim for its hydro and immersion systems; the HashTub page says only 'near-silent'); dimensions (immersion enclosure only; tub size depends on the configuration); launch date (public debut at Heatpunk Summit, 27-28 Feb 2026; no first-delivery date published); production status (sold through a paid waitlist; Snorkel says only a small number of heat units are available and gives no delivery dates. Outside sources show only Snorkel's own install at The Space, Denver, finished on 21 February 2026 for the Heatpunk Summit, and the Bitcoin 2026 floor model; in June 2026 Snorkel wrote that one soak 'lead to another Hashtub', but no customer delivery has been reported); where it's made (Hashrate House says the heat system is designed and assembled in the USA; Snorkel gives only its Seattle workshop address); weight (not published); frequency (not published); operating temperature (not published); colours (not published).
