The distance between the heater and the upper wood board is around 10cm, so the board is uneasy to be smoked or even burnt. |
Less space left. |

Reflector behind the infrared emitter is made by aluminium, excellent heat reflection performance |
Made by zinc-plating steel sheet or normal stainless steel sheet, poorer heat refelection performance. |

| Package |
Every package passes the "Droping Test" ensuring the best protection effects onto sauna during transportation. |
Few does the droping test. |
Royal Saunas have been looking for the best packaging way. For 3-person sauna and above, we use 3 cartons. Doing this increases cost, however we think it is worthy. Consumers in USA will get a sauna as good as that in our factory, China. |
