    Default Alternative to Western red Cedar

    has anyone made a hot water tub using timber other than Western Red Cedar?

    I am planning to make a hot water tub but the WR Cedar is very pricey over here, looking at $3600 NZD + gst per m3

    I have easy access to larch and redwood.

    Cheers

    When you say “redwood” do you mean Californian Redwood? It’s quite similar. Western red cedar and Oregon prices have skyrocketed because most of those huge wildfires in the USA have destroyed the plantations of those timbers. We can’t get much over here either

    Thanks I have been reading up the the Redwood it seems to be similar to WRC in terms of property. less than half price of Cedar over here.

    What about Alaskan Yellow Cedar? Bunnings did sell it about 15 years ago. I think its gone more specialty suppliers now.

    Redwood sourced in NZ is possibly locally grown planation timber. Ditto for larch.

    I believe one of the benefits of using WRC is it's antimould and antifungal properties. And if kept wet WRC retains most of its colour.
    I'm not sure that Larch (locally grown or imported) has similar properties and locally (to NZ) grown Redwood may also be lacking in the key antifungal antimould extractives.

    The risk you are trying to manage is that whatever wood you end up using discolours on account of mould or bacteria.


    Sorry, I can't be more helpful

    Thanks Ian, I may just have to bite the bullet and buy them from the merchant... the most expensive timber ever bought..

    .....

    Until about 60 years ago, In Tasmania laundry troughs and scullery bench tops were traditionally made from Huon pine (Lagarostrobos franklinii) and occasionally (rarely) from King Billy pine (Athrotaxis selaginoides). Huon is now sometimes used to fashion very expensive hot tubs and baths. It costs a lot more than your WRC!

    I know absolutely nothing about the NZ timber market, but I presume that a hot tub would require quite high quality timber - what I know as "boat building grade"- a higher grading than "select". I quickly googled Bunnings NZ and the highest grade timber that I could find was "clear" grade radiata 90x42mm at NZ$18.50 per linear metre. This is $4,894 per cube, including GST.

    The WRC was $3,600 net, or $4,140 including 15% GST.

    Providing the quality is acceptable, that WRC may not be all that expensive.

    Do you have any Hemlock over there? It’s quite similar to Western Red cedar. Spruce would be good too but the price would be up there with WRC as it comes from the same place.

    If you haven't already purchased the WRC from your wholesaler, check the antibacteria, antimould properties of the different wood species you have local access to.

    I've a vague memory that WRC (Thuja plicata) replaced Californian Redwood (Sequoia sempervirens) for hot tub construction when Californian Redwood became commercially scarce. New Zealand plantation grown Sequoia sempervirens may be suitable for the hot tub.
    I could b wrong, but the cost differential would be worth at least an hour of your time to research the issue.

    Timber from Bunnings are super expensive, everytime I go to Bunnings I feel bad seeing those customers buying 1-2 pieces of pine paying that kind of money... in the past I have been buying a bolt and nut set from Bunnings for $1, I recently found out I can get them in bulks from the supplier for $0.08.

    Thanks Ian, I have been doing that, not a lot of info about locally grown timber and how antifungal/antigbacterial they are. but a lot of info about oversea timber...
